Local photographer Muhammad Malik was coming out of the subway when he happened upon the immediate aftermath of this morning's deadly shooting near the Empire State Building. He promptly uploaded a photo of one victim, bleeding on the pavement, to Instagram, complete with a crass caption quoting the rapper Nas: " " On Facebook, he added, "MAN DOWN! SHOTS FIRED!" 
 
 Soon after, the news organizations came calling for permission to run the picture. "OMG, reporters are calling me from all over the country!" he wrote. "Making major deals! #chaching." But when reached by Daily Intel to ask about his rate, Malik was more subdued. "Actually to be honest, it's free — I don't even care," he said. "That happened this morning, at this point it's just too much for me." He also insisted he wasn't being offensive. ||||| Late Friday, a UPS driver noticed that a package being delivered was addressed to Farook's townhouse and turned around to return it to a distribution facility, San Bernardino Police Chief Jarrod Burguan said in a tweet. The package was held in isolation, and the sheriff's office deployed bomb technicians to inspect the package out of an abundance of caution.

 (CNN) -- The San Bernardino, California, mass shooting is now being investigated as "an act of terrorism," FBI official David Bowdich said Friday. 
 
 Bowdich said the FBI "uncovered evidence ... of extreme planning." 
 
 He said some phone conversations between at least one of the shooters and other people are being investigated. The announcement means the FBI has become the lead investigative agency, taking over from San Bernardino police. 
 
 "As of today, based on the information and the facts as we know them, we are now investigating these horrific acts as an act of terrorism," said Bowdich, assistant director of the FBI office in Los Angeles.

 The announcement came several hours after a revelation about Tashfeen Malik, the female shooter in the Wednesday massacre that left 14 dead and 21 wounded. 
 
 She posted a pledge of allegiance to ISIS leader Abu Bakr al-Baghdadi on Facebook while the shooting was happening, three U.S. officials familiar with the investigation told CNN. 
 
 Malik's post was made on an account with a different name, one U.S. official said. The officials did not explain how they knew Malik made the post. 
 
 A Facebook official told CNN that a post that went up about 11 a.m. Wednesday that violated the company's community standards that prohibit the promotion of terrorism or the glorification of violence. It was taken down Thursday. 
 
 The official said he couldn't go into details about the nature of the post. The official said Facebook is cooperating with law enforcement. 
 
 The mass shooting may have been inspired by ISIS, a law enforcement official said, but none of the officials said ISIS directed or ordered the attack. ISIS has called for people worldwide to launch attacks in its name but isn't known to have claimed credit for what happened in San Bernardino.

 Malik and her husband, Syed Rizwan Farook, burst into a holiday party for the environmental health department he worked for and opened fire. They were killed elsewhere in a shootout with police. 
 
 No one has been arrested in connection with the massacre, but authorities say arrests are possible. 
 
 "This is looking more and more like self-radicalization," a law enforcement official said. 
 
 Farook's relatives didn't know the couple held radical views and have no idea why the couple burst into the party for Farook's co-workers and viciously opened fire, family lawyers said. Nor did the family know the couple had a makeshift bomb lab in the apartment they shared with their 6-month-old daughter and Farook's mother. 
 
 "It just doesn't make sense for these two to be able to act like some kind of Bonnie and Clyde or something," Farook family attorney David S. Chesley told CNN's Chris Cuomo. "It's just ridiculous. It doesn't add up." 
 
 Another official said authorities haven't ruled out that others may have influenced this radical view. In addition, the law enforcement source said investigators think a workplace issue with religion may have sparked the killings. 
 
 Officials: Farook talked to person investigated for terror 
 
 Neither Farook nor his wife had gotten into trouble with the law, according to police. Neither was on any list of potentially radicalized people. 
 
 But it's not known what connections Malik, who was born and raised in Pakistan and moved to Saudi Arabia about the age of 19, had with any terrorists or groups. 
 
 Investigators are exploring Farook's communications with at least one person who was being investigated for possible terror connections. Some were by phone, some on social media. 
 
 "These appear to be soft connections," an official said, meaning they were not frequent contacts. Farook's last communication with the contacts was months ago. 
 
 A federal official said Farook has "overseas communications and associations," but it's not yet clear how relevant they are to the shootings. "We don't know yet what they mean," the official said. 
 
 Family lawyer Mohammad Abuershaid said that Farook traveled twice to Saudi Arabia -- first in 2013 for the Hajj, the annual pilgrimage to Mecca that Muslims are required to make at least once in their lifetimes, then again to marry Malik, whom he'd met through an online dating service. 
 
 Bowdich said that he went to Pakistan, as well, though Abuershaid denied that. 
 
 Did a workplace dispute boil over? 
 
 The shooters didn't make it easy for authorities: The hard drive from their computer is gone, and two relatively new cell phones were found smashed in a garbage can near one of the crime scenes, law enforcement officials said. 
 
 Bowdich called this an attempt to destroy "digital fingerprints." 
 
 Photos: San Bernardino shooting Police officers stand guard as they investigate a suspicious vehicle in Redlands, California, on Wednesday, December 2, after a mass shooting in nearby San Bernardino in which 14 people died and 21 were injured. The shooting took place at the Inland Regional Center, where employees with the county health department were attending a holiday event. The two shooters -- Syed Rizwan Farook and his wife, Tashfeen Malik -- were fatally shot in a gun battle with police hours after the initial incident. Farook worked for the county health department.

 Authorities haven't ruled out what President Barack Obama called "mixed motives," meaning that Islamic radicalism and workplace grievances both could have driven the attack. 
 
 San Bernardino Police Chief Jarrod Burguan had earlier said there were indications Farook appeared angry when he suddenly left the holiday luncheon at Inland Regional Center, only to return heavily armed with his wife. 
 
 But the chief on Friday played down that possibility, saying many people at the holiday party said they saw no evidence of an argument. 
 
 Farook family lawyers didn't speculate on his reasoning, though Chesley did say that "at some times co-workers have done silly things, like made fun of Syed's beard." 
 
 One of Farook's colleagues killed in the attack, Nicholas Thalasinos, liked to discuss religion and politics. Farook and Thalasinos, reportedly a devout Messianic Jew, had a "heated, passionate" discussion about politics and religion a few days earlier, said Kuuleme Stephens, a friend of Thalasinos, who called him at work while Thalasinos was in the middle of the conversation. 
 
 The men were sticking by their strongly held positions but were not fighting, Stephens said. 
 
 Thalasinos' widow, Jennifer, said he was quite verbal about terrorism. "He's very upset about what ISIS has been doing and the radicalized Muslims," she said.

 Even those who knew Farook best didn't see anything to suggest something nefarious, according to family representatives. 
 
 That included Farook's mother, who thought nothing of it when the pair had her watch their 6-month-old girl while they went to a doctor's appointment, Abuershaid said. The lawyer didn't know if there ever was a doctor's appointment -- only that the mother initially worried that Farook had gotten shot, not that he was doing the shooting. 
 
 Chesley expressed surprise that Malik, whom he described as being "about 90 pounds, so it's unlikely she could even carry a weapon or wear some type of a vest or do any of this," could have been an active participant in the horror. 
 
 A mob of reporters was allowed inside Farook and Malik's rented Redlands townhouse Friday, getting a glimpse at how they lived. 
 
 Much of it appeared relatively mundane -- from a hanging clock to couches to many baby items like a crib, ExerSaucer and other toys. 
 
 But there were also hints of something more, like shattered glass, boarded-up windows and lists of items seized by federal authorities. The FBI always leaves behind such lists after a search. 
 
 Authorities searched the house earlier and found pipe bombs, thousands of rounds of ammunition inside the house and more guns. 
 
 The FBI inventoried what they found and returned custody of the home to the landlord. The inventory listed parts for guns, about 5,000 rounds of ammunition, tools, gun boxes, holsters, electronics, Christmas lights, a thumb drive, a laptop and a cellphone with a SIM card missing. 
 
 Asked whether authorities were concerned about media entering the couple's apartment, Bowdich replied: "Once we turn that location back over to the occupants of that residence or once we board it up, anyone who goes in at that point has nothing to do with us." ||||| Story highlights A woman says she was chatting with Steven Ercolino when a man opened fire

 Police: Investigation under way after officer shot nine rounds while another shot seven 
 
 On a busy Friday morning in Manhattan, nine pedestrians suffered bullet or fragment wounds after police unleashed a hail of gunfire at a man wielding a .45 caliber pistol who had just killed a former co-worker. 
 
 The officers unloaded 16 rounds in the shadow of the Empire State Building at a disgruntled former apparel designer, killing him after he engaged in a gunbattle with police, authorities said. 
 
 Three passersby sustained direct gunshot wounds, while the remaining six were hit by fragments, according to New York Police Commissioner Ray Kelly. All injuries were caused by police, he said Saturday. 
 
 One officer shot nine rounds and another shot seven. 
 
 Police identified the gunman as Jeffrey Johnson, 58, who was apparently laid off from his job as a designer of women's accessories at Hazan Import Co. last year. 
 
 Johnson, who served in the U.S. Coast Guard in the mid-1970s, had two rounds left in his pistol. It holds eight, Kelly said. 
 
 Police identified the slain co-worker as Steven Ercolino, 41, who had apparently filed a prior complaint against his assailant, claiming that he thought Johnson would eventually try to kill him.

 Both men had filed harassment complaints against each other in April 2011, Kelly added. 
 
 Ercolino was listed as a vice president of sales at Hazan Import Corp., according to his LinkedIn profile. 
 
 "It's not something that should happen to a loving person like that," said his brother, Paul. "He's going to be so missed by everybody. He was a light of so many lives." 
 
 His longstanding dispute with the gunman "apparently centered on the fact that Ercolino was not selling -- at least in Johnson's opinion -- as much of his product ... as he wanted him to," Kelly said. 
 
 The suspect lost his job last year at Hazan "as a result of downsizing" but continued to return to the company regularly, engaging in "a confrontation with Ercolino virtually every time he went back." 
 
 The violence erupted Friday morning just as visitors began to queue up to ascend the famous New York skyscraper in one of Manhattan's busiest neighborhoods. 
 
 Six of the injured were treated and released at hospitals by Friday evening, while three others remained hospitalized, Kelly added. 
 
 One of those wounded, Erica Solar, was on her way to get a cup of coffee at Dunkin' Donuts when a bullet tore through the back of her leg, her brother said. The Manhattan receptionist is being treated at the city's Bellevue Hospital. 
 
 Others like Robert Asika, a 23-year-old city tour guide, were on their way to work and got caught in the crossfire. 
 
 "When I turned around, I saw a guy reach in his suit and he pulled out a gun," he told CNN affiliate WCBS-TV . "I guess he shot at the police officer. And the police officer shot him. And one of them shot me in the arm, and I fell." 
 
 Irene Timan recalled to CNN affiliate WABC how she was walking down West 33rd Street and chatting with Ercolino on Friday morning, when she spotted Johnson. 
 
 "I was like, 'Oh my God, that's Jeff Johnson.' And I was like, 'He's going to kill him, he's going to kill him, I know he's going to kill him,'" said Timan, who knew there was "bad blood" between Johnson and Ercolino but didn't know why. 
 
 Then, as Ercolino was talking to Timan in mid-sentence, Johnson fired at him -- "right next to me," she recalled. 
 
 Kelly, the police commissioner, said that Johnson -- who was wearing a business suit and carrying a briefcase as he waited -- shot Ercolino once in the head and then in the torso. 
 
 An emotional Timan said Saturday that she has been replaying the incident "over and over in my mind. And I thought, 'Maybe you could have kicked the gun out of his hand and Steve would have only gotten shot once instead of five or six times.' ... I just ran, I didn't know what else to do." 
 
 Johnson then walked east, before eventually turning north. A construction worker was among those who dashed after the gunman after the initial gunshots. Eventually, the worker alerted two police officers in front of the Empire State Building that the suspect "just killed a man around the corner," Kelly said. 
 
 The police commissioner said the suspect pulled his gun out of his briefcase as the officers approached, pointing at them. The officers then fatally shot Johnson. 
 
 A brief surveillance video released Friday night by police shows the man walking behind a large planter on a busy street. He appears to point something as two officers approach, coming to within a few feet of him. Then, as bystanders run in all directions, the man falls abruptly to the ground after apparently being shot. 
 
 Witnesses said police shot Johnson at least three times. 
 
 "I heard the gunshots," said Anika Basu, who was on a bus near the building when the shooting happened. "I looked toward the left and saw three people fall. ... The whole entire crosswalk emptied and people were running. 
 
 When she heard the shots and saw people running, this time toward her, Timan said she feared Johnson was "going on a shooting spree." 
 
 "And I really thought he was coming back for me," she said. 
 
 Police say Johnson used a semiautomatic handgun and was carrying extra ammunition in his briefcase. He purchased the weapon legally in 1991 in Florida but did not have a permit to carry it in New York City. 
 
 The former Manhattan resident did not appear to have had a criminal record, but authorities were still checking, Mayor Michael Bloomberg said. 
 
 Johnson's neighbor, Gisela Casella, described him as a quiet animal lover whose death left her "shocked." 
 
 "He was the nicest guy. He must have snapped or something. I don't know," she said. 
 
 His landlord, Guillermo Suarez, said he lived alone and that he'd seen Johnson leave the building around 8 a.m. in a suit. 
 
 By around 9 a.m., the shootings had prompted local and federal authorities to close several streets around Fifth Avenue and West 34th Street, snarling traffic in the heart of Manhattan. 
 
 The Empire State Building is one of the most famous skyscrapers in the world and one of New York's best-known tourist attractions. 
 
 Each year, about 4 million people visit the building's two observation decks. At more than 1,453 feet tall, the landmark building reaches more than a quarter-mile into the sky.
– One of the more widely used images from today's shooting spree near the Empire State Building shows a wounded man on the street being being tended to by a woman. Turns out it was shot by local photographer Muhammad Malik, who immediately uploaded it to Instagram with this not-so-sensitive caption, a play off of lyrics by Nas: "They shoot, aw made you look! No really tho. Dude got popped!" That drew plenty of online criticism, as did his Facebook boasts (complete with hashtag #chaching) about cashing in on the photo. "Let's be clear everyone, I didn't shoot anyone, I just took a photo, don't hate me, hate the actions that caused me to get a picture like that," he wrote in response. "It's cameras that allow all of us to see what's going on in parts that we would never venture into or otherwise wouldn't think twice about." When Daily Intel caught up with him, a "more subdued" Malik said he would "probably not" make any money from the image. "I don't think it was insensitive," he said. "It's New York, I just took a photo." As for that caption, "it was just a comment."
