Input: A Tampa teenager has been arrested and charged with plotting to kill two school officials and 30 students with bombs on the first day of school scheduled for next week in what would have been the most serious school attack since the Columbine massacre. 
  
 Jared Cano, 17, wrote a manifesto that detailed his plans for his attack starting at 5 a.m. next Tuesday, Police Chief Jane Castor said at a news conference today. The manifesto allegedly included information about the layout of Freedom High School in Tampa, Fla., and where exactly Cano was planning to place bombs in the school of roughly 21,00 students. 
  
 Castor also said they recovered bomb making material from his home including fuses, timers, shrapnel, accelerant and plastic tubing. No firearms were found in his family's apartment, police said. 
  
 "The plot very serious. He could have done all the damage he intended to do," Castor said. 
  
 The arrest on Tuesday came just hours after someone alerted police about Cano's alleged plot, Castor said. After a tip came into Tampa Police Department's call center that Cano was plotting to bomb the school, detectives immediately called a bomb squad to his apartment. The tipster's identity has been kept confidential but that person was praised today as a "hero." 
  
 "It's someone who had information and they felt strongly enough to call the Tampa Police Department," Castor said. 
  
 Police said that Cano specified in his manifesto his goal of surpassing the number of students who were killed and injured during the 1999 Columbine High School massacre. 
  
 On April 20, 1999, Columbine High School seniors Eric Harris and Dylan Klebold, wielding automatic weapons, slaughtered 12 students and one teacher. Another 24 were wounded in the 45 minute rampage. 
  
 Plot for Tampa School Massacre Uncovered 
  
 Cano is the latest student to express admiration for the Columbine killers. Seung-Hui Cho sent a tape praising Klebold and Harris before going on a shooting spree at Virginia Tech that left 33 people dead in 2007. 
  
 The teen's manifesto targeted two individuals "in the administration at Freedom High School," both of whom have been alerted that they were target, the chief said. Cano expressed feelings of "ill will" towards both of them in the manifesto. 
  
 He also targeted 30 students for death, the police said. 
  
 The manifesto detailed his minute-by-minute plan of attack, starting at 5 a.m. next Tuesday. It included the layout of Freedom High School and where exactly Cano was planning to place bombs in the school, Castor said. 
  
 She also said that the "materials found at [his] home were serious enough to do the job he wanted to do," and added that everything was purchased legally. 
  
 Police said they have no reason to believe that anyone else was involved in the bomb plot. They reported that the family had been cooperative. Castor said that Cano's mother, who he lives with, did not know that her son had materials to build a bomb in his room. 
  
 Cano has been charged with threatening to throw, project, place or discharge a destructive device. He also faces charges for possession of bomb-making materials, cultivation of marijuana, possession of drug paraphernalia and possession of marijuana. 
  
 Cano has been arrested in the past, police said, and has an "extensive criminal record." His most recent arrest was for burglary. Tampa police confirmed that Cano had previously broken into a house and stolen a firearm. The victim, a convicted felon, did not press charges. Cano had also previously been charged with carrying a concealed weapon, a taser, and the possession of marijuana. 
  
 Castor said that Canon was already a person of interest to them, in that he was part of their group of offenders that Tampa Police keeps an eye on. 
  
 In response to Cano's mental status, Castor only said, "we are not in the business of diagnosing the mental health of an individual." 
  
 But Cano's recent Facebook status messages may indicate emotional disturbance. "My life stays on repeat its gettin old :/" he posted on Monday at 12:11a.m. 
  
 Tampa Student Had Manifesto for Murder: Cops 
  
 Under his favorite quotations on Facebook, he listed, "lessons not learned in blood are soon forgotten." 
  
 Cano also admitted to his use of marijuana on his Facebook profile, posting "i love me some weed haha" on Aug. 13 at 11:45 a.m. 
  
 But on Tuesday, Cano posted to his wall, "i jut did the dumbest thing ever!" 
  
 According to Christopher Farkas, Freedom High School principle for the past three years, Cano was suspended from that school in March 2010 for an off-campus incident. Police confirmed that he was expelled from school for his previous burglary. 
  
 In a press conference today, Farkas, who knew Cano, said, "there are threats that happen" involving the school, but that "95 percent of time, they're not real." 
  
 Farkas said school will open on Tuesday as scheduled, with increased police security on campus and counselors available to students if necessary. Electronic messages have also been sent out to parents of students informing them that the school is working with the Tampa Police Department to keep the school safe. ||||| By John Barry, Alexandra Zayas and Jodie Tillman, Times Staff Writers

 TAMPA — They found ingredients to build pipe bombs. They found schematics for Freedom High School. They found a manifesto, a plot to kill even more people than the 13 massacred in 1999 at Columbine High. 
  
 Police this week thwarted a "catastrophic event the likes of which Tampa has not seen," Chief Jane Castor said at a news conference midday Wednesday. 
  
 An hour earlier, skinny, shaggy-haired Jared Cano had appeared in juvenile court, accused of it all. 
  
 The 17-year old, who was expelled last year from Freedom, buried his face in his lap until he was called before the judge. He had been arrested Tuesday in front of his mother and had spent the night in juvenile detention. The state had not yet decided whether to prosecute him as an adult. He hung his head as a prosecutor listed what police found in his room. 
  
 He stood alone. 
  
 Circuit Judge Tracy Sheehan asked where his parents were. 
  
 His mouth quivered. He said he didn't know.

 Police got the anonymous tip at 11:50 a.m. Tuesday: An expelled Freedom student was planning to discharge explosives at the school in Tampa Palms. They said he had specific plans for violence next Tuesday, the first day of school, targeting two faculty members and any nearby students. 
  
 At 6:30 p.m., the suspect's mother consented to a search of their Cypress Run at Tampa Palms apartment, where officers found materials to construct pipe bombs: a fuel source, shrapnel, plastic tubing and timing and fusing devices. They also found a journal with a minute-by-minute plan and "disturbing statements" about his intent to kill. 
  
 Cano did not make admissions to police, but prosecutors say he verbally had acknowledged his plan to discharge a bomb and cause mass casualties. 
  
 Court records show that Cano's parents, Michelle and Alexander Cano, divorced in 1998 and the mother was granted custody of two children. His mother is listed as a math teacher at Riverview High School in south Hillsborough. Attempts to reach her and other family members were not successful. 
  
 His father has been arrested numerous times, the first two for contempt of court involving domestic violence injunctions around the time of the divorce. He has since been convicted of DUI with property damage or personal injury. 
  
 Police think Cano, who they said is now home schooled, was acting alone. 
  
 Hillsborough school officials joined police in crediting the anonymous tipster, noting the importance of public vigilance in preventing a repeat of Columbine. Freedom principal Chris Farkas said he thanks that tipster for courage. 
  
 Farkas said he thinks teachers would have stopped Cano if they had seen him on campus in north Hillsborough County. 
  
 Had the plan played out, the police Regional Bomb Team reports, Cano's materials were "capable of taking multiple lives." 
  
 In the apartment, police also found a marijuana growing operation, with lights, plants and a digital scale. 
  
 Cano faces charges of possessing bombmaking materials; threatening to throw, project, place or discharge a destructive device; cultivating marijuana; and possessing marijuana and drug paraphernalia. 
  
 The charges are not his first.

 Cano's name has been in police reports since 2007: 
  
 Stealing CDs. Walking around his apartment complex with a stun gun. Yelling profanities at his mother from the backseat of a patrol car. Stashing a pipe in his pants. 
  
 He was in 10th grade at Freedom in January 2010 when he told police he got bad grades because he does not pay attention. He said he had been diagnosed with attention deficit disorder but was not taking medication. 
  
 In March 2010, Cano was expelled. His principal didn't disclose the reason but said it related to a police matter. Records show that was the month he was accused of stealing a gun from a friend's grandfather. When police showed up at Cano's house, the teen met them shirtless, wielding an aluminum baseball bat. 
  
 Police said they repeatedly ordered Cano to drop the bat and had to use force. Police said Cano admitted stealing the gun, which they found with its serial number filed off, but there were complications in the case. 
  
 Cano has never been convicted. He has undergone pretrial diversion and faced sanctions but was not under any at the time of his arrest Tuesday night. 
  
 By Wednesday, the news had reached his friends. 
  
 "I always knew there was something a little bit off about him," said Nicolette Thyne French, 17. 
  
 French, a Chamberlain High School cheerleader, said she had known Cano since they attended Adams Middle School, but they lost touch after he left. 
  
 "He faked his own death," she said, explaining that a few years ago he renamed his MySpace page "RIP Jared Cano," and he didn't respond to friends when they tried to contact him. 
  
 French said they recently connected on Facebook, and he started to get attached. She felt he was emotionally unstable. "He wanted to be with me — like, more than friends. . . . Told me he loved me and all this stuff. I was just telling him, 'I can't be with you.'. . . 
  
 "It might have been a breaking point for him." 
  
 He wrote her off as a friend, she said, but reached out this week and asked her to forgive him. 
  
 French said she was surprised by his arrest and thought he just wanted attention. 
  
 On his Facebook page, Cano chronicled his life. He wrote extensively about marijuana and posted photos of himself smoking out of a pipe, drinking out of a bottle of Olde English malt liquor and holding a large knife. 
  
 The morning before his arrest, Cano wrote on his Facebook page: 
  
 i jut (sic) did the dumbest thing ever!

 In court Wednesday, the judge asked if he had anything to say. 
  
 "I don't know what to say. . . ," the teen said. 
  
 His public defender said, "He doesn't want to say anything right now." 
  
 The judge asked if he wanted to say anything without speaking about his charges, and the teen began to speak: 
  
 "The plan wasn't … ," 
  
 But his public defender interrupted: "Don't say anything," she said. 
  
 "I can talk," Cano said. "I'm allowed to say what I want." 
  
 The public defender asked the judge for a second to talk to him. She whispered in the teen's ear, and then she said, "He has no comment." 
  
 Cano is being held in secure detention. 
  
 He will return to court on Sept. 2 for an arraignment.

Output:
Authorities in Tampa say they busted up a teen's Columbine-level plot to attack his former high school, reports the St. Petersburg Times. Police arrested a 17-year-old expelled student who had a cache of bomb-making materials at his home and a journal detailing his plans to bomb Freedom High School on the first day of school next week and kill more victims than the two Columbine assailants did in 1999—13. "We were probably able to thwart potentially a catastrophic event the likes of which Tampa has not seen," said the local police chief. "And hopefully never will." A tipster alerted police to the plot yesterday morning, notes ABC News. The suspect, Jared Cano, faces a host of felony charges—including marijuana cultivation. Police say they also found a sophisticated pot-growing operation in his room.
