 Gunfire at a San Francisco hospital ended Wednesday with police launching flashbang grenades on the suspect who was armed with a stolen rifle. That gunman is dead.It all started Wednesday afternoon at the Big 5 Sporting Goods store on El Camino Real in San Bruno. Police say the suspect robbed the store and stole that rifle. He then took off for St. Luke's Hospital in San Francisco's Mission District and that's when he found himself in a standoff with SWAT officers.Police have reopened Cesar Chavez in front of Saint Luke's Hospital. People were trapped inside the hospital with an active shooting going on outside.A construction worker at the new Saint Luke's Hospital says he saw a suspicious man and possibly a gun and called 911."Sirens and police vehicles, screeching tires, it was crazy," said Eduardo Sosa, a witness.The police chief described what officers saw."Reponding officers rushed to the scene and heard shots fired as they arrived," said San Francisco police Chief Greg Suhr. "They exited their vehicles and looked up and atop the construction elevator was a suspect in white coveralls holding a rifle and pointing it at the hospital."Three officers fired on the man. Then, flash bangs were deployed to ensure he was no longer a threat, as his rifle was still within reach. The man was dead.Sonja Holman and her 11-year-old son were inside the hospital."Everybody moved away from the windows and then they said they're not letting anybody leave the hospital or anybody come back to the hospital and then you just heard all this, it sounded like a bomb," Holman said."I was listening to music with my headphones on and I heard a loud bang and I stopped the music and I heard it again. It was loud. It sounded really close," said Travion Gray, a witness.As the situation was unfolding in San Francisco the San Bruno connection came to light. The suspect matched the description of a man who, armed with a handgun, had just robbed a Big 5 Sporting Goods store."We have no idea why he did what he did at the construction site, but he did steal firearms and shotgun shells from Big 5," Suhr said.Police believe the man drove from San Bruno to Saint Luke's and they found his vehicle at the scene, possibly a white pickup truck that was being scrutinized by officers Wednesday night.Police searched for a second shooter, but they searched the construction site and believe the man they killed acted alone. No one else was hurt.Several witnesses captured the SWAT action on their cell phones.From his apartment window, Jonathan Morey watched the action unfold at the St. Lukes Hospital construction project. He shot video of police officers walking up the stairs towards a construction elevator where it's believed a gunman was firing shots."My roommate and I heard the commotion on the third floor here," Morey said. "Initially, we saw a couple of construction workers on the top floor of the construction. They looked like they were running away and maybe getting behind a barricade, or something to protect them."Nicola Imseeh says he took iPhone video about 100 yards away from the shooter. He says people, on the ground, were running from the shots."Like three shots," Imseeh said.Imseeh moved to San Francisco, two weeks ago, from the West Bank. Morey says snipers set up across the street because they had a clear shot at the gunman. Both Morey and Imseeh heard two quick shots which they believe killed the gunman and ended the standoff. ||||| UPDATE 7:44 P.M.: San Francisco police Chf.

 San Francisco police responded to reports of shots fired near the hospital in the 3500 block of Cesar Chavez Street around 4:30 p.m. 
  
 According to San Francisco police Chief Greg Suhr, the suspected gunman, identified as a man in his late 20s, was believed to be the same suspect in a robbery at the Big 5 Sporting Goods store in San Bruno earlier Wednesday afternoon. In that incident, Suhr said, the suspect, who was armed with a handgun, robbed the store of a shotgun and ammunition. He then made his way to San Francisco, Suhr said, where he somehow got onto the roof of a service elevator and opened fire as San Francisco officers responded to the scene. 
  
 The construction site is the replacement hospital for St. Luke's, hospital spokesman Jim Macksood said, and is slated to open in 2019. 
  
 "We have no idea why he did what he did," Suhr said. "It's very fortunate that no one was injured or killed." 
  
 Suhr said three San Francisco police officers opened fire on the suspect just after 5 p.m. as he pointed the shotgun downward. No one else was injured in the incident, Suhr confirmed. The handgun believed to be used in the San Bruno robbery was found on the suspect, Suhr added. 
  
 San Bruno police received a report of an armed robbery around 3:51 p.m. at the Big 5 Sporting Goods store at 855 El Camino Real. Officers said that a suspect entered the store, produced a handgun, and stole a firearm. They described the suspect as a light-skinned male wearing white overalls and a black sweatshirt and said he fled the store on foot.

Police fatally shot a man climbed to the sixth floor of a construction site and aimed a gun at a hospital in San Francisco on Wednesday, authorities say, reports KRON. The man first robbed a nearby sporting goods store in San Bruno with a handgun, making off with a rifle and ammunition, before scaling the incomplete building around 4:15pm, police say, reports the San Francisco Chronicle. Officers arrived to find the man, who was wearing white overalls, pointing the rifle at nearby St. Luke's Hospital and "heard shots fired," police chief Greg Suhr tells ABC7. Authorities say the man also pointed the gun at police from a construction elevator before three officers opened fire. Authorities also used flash bangs to neutralize the man before confirming he was dead, police say. The Chronicle reports a camera facing the construction project caught footage of a man slumped against the side of the elevator at 4:30pm. Another frame shows two officers on the building's roof around 4:45pm; one is pointing a rifle at the man. Officers later confirmed that the gunman fired one round—they wouldn't say where that shot was directed—but that no one was hit. "It's very fortunate that no one was injured or killed," Suhr tells the San Jose Mercury News. "We have no idea why he did what he did." The man appeared to be Hispanic and in his late 20s, police say. The building where the shooting took place will become a replacement hospital for St. Luke's in 2019.
