Gunfire erupts, leaving 2 officers dead: New details into how chaos unfolded in Salina

SALINA, N.Y. — An eruption of gunfire on a quiet suburban street in the Town of Salina sent families scrambling. Parents dragged their kids to the basement of their homes, trying to avoid getting hit. A new video shows just how dangerous that street became in just a matter of seconds, leaving two officers dead on Sunday evening.

Syracuse traffic stop spirals into deadly shootout: A timeline of Sunday night's events

Multiple people who live on Darien Drive, where alleged shooter Christopher Murphy was living, had similar accounts of two rounds of gunfire that line up with how officials have described the incident. Neighbors said that the first round was short, with just a few pops that could have been described as fireworks. The second was like thunder; a video shot by a neighbor from behind their blinds captures the audio of around 10 shots being fired before it all becomes hard to distinguish, with dozens of rounds going off in a matter of just eight seconds.

This was the firefight around the front of the house where Murphy, 33, was living. Once the gunfire stops, the video shows two officers checking on what appears to be Murphy's body across the street from his home, putting him in handcuffs. Then one of them cries out, realizing that Officer Michael Jensen had collapsed in the driveway behind them.

"Jensen! Jensen!" one of the officers yelled, running back to their fallen colleague.

The first, slower round of gunfire was likely what claimed the life of Onondaga County Sheriff's Deputy Lt. Michael Hoosock. Sheriff Toby Shelley said that Murphy ambushed him after he took a position behind a tree in a neighbor's backyard to the east of Murphy's home.

According to Deputy Douglas Roser, Murphy fired on Lt. Hoosock multiple times before repositioning on his back deck, gaining a clear line of sight and striking the veteran deputy. Two other deputies had taken up positions in a backyard to the west, but their view of Murphy was cut off by a part of the home.

According to Deputy Roser, Murphy then emerged out his own front door and opened fire on two Syracuse Police officers who were waiting in the driveway area. One of them was Officer Jensen. Murphy managed to run past them while firing until he was out in the street; it was then that two other Syracuse Police officers, positioned behind trees, were able to return fire.

Officer Jensen also returned fire himself, with investigators still determining who actually struck Murphy. This is all in line with the audio from the neighbor's recording, which begins with about ten rounds coming from what an expert believes is Murphy's AR-15, before police service weapons join the barrage.

Rifle used in fatal shooting of 2 officers had illegal magazine attached

The gun in Murphy's hands was a Springfield AR-15, according to Sheriff Shelley. On Tuesday, deputies and Onondaga County District Attorney Bill Fitzpatrick confirmed that the magazine was illegal, capable of holding 40 rounds. That's four times the legal limit in New York State.

According to a firearms expert, this is a semi-automatic rifle that was largely banned under the NY SAFE Act, though roughly 6,000 are legally grandfathered in and registered. This particular gun was not registered to Murphy; investigators are now working to see if the gun had been legally owned by either of Murphy's parents, who own the home.

Deputies recovered at least six other rifles, boxes full of ammunition and a crossbow from the home on Tuesday. Deputy Roser said that the guns were kept in gun safes, one in Murphy's bedroom and one in what is presumed the bedroom of his parents. According to neighbors, they do not live there full time and have been out of state.

As for the rifles, Deputy Roser said that there were multiple guns that seemed ideal for hunting, and at least one other AR-style weapon. Multiple neighbors told the I-Team that Murphy's father was an avid hunter; investigators say it will take time to confirm if any of the weapons were legally owned.

Officers first established the perimeter around Murphy's home after spotting ammunition in his car, one that was tracked after Murphy failed to comply with a traffic stop in Syracuse's Tipperary Hill neighborhood. Lt. Hoosock was the one to find the car.

Less than half an hour later, the deadly gunfire began.
