PHILADELPHIA- On Tuesday, March 1, 2022, at approximately 7:24 PM, Officers #1, #2, #3, and #4, all assigned to the South Task Force, were dressed in plainclothes, operating an unmarked vehicle in the area of 18th and Johnston Streets, in reference to an on-going VUFA investigation.
While in the area, the officers observed two males standing on the northeast corner of 18th and Barbara Streets. Officers observed that one of the males was wanted for questioning in reference to the VUFA investigation. The officers drove towards the males and stopped a few feet north of Barbara Street, on 18th Street. Officer #2 (driver) activated the red and blue emergency lights on the unmarked vehicle. At that point, they heard gunfire and glass shattering from the rear passenger window. Officer #3, positioned as the rear passenger, was struck by shards of glass in his face and eyes. Officer #2 and Officer #1 (rear driver’s seat) exited their vehicle and discharged their firearms at Thomas Siderio (12/W/M), who was still in possession of his firearm, as he fled on foot east on the north sidewalk. Officer #1 pursued Siderio, and was discharged two times, striking Siderio in the upper right back area one time, with the bullet exiting from the left chest area. He was transported by police to Presbyterian Hospital, where he was pronounced deceased at 7:29 PM.
Officer #3 received treatment at Presbyterian Hospital and was released.
Note: The projectile that struck the unmarked police vehicle had a perforating hole through the rear passenger window’s glass. The projectile struck the inner doorframe, then perforated the passenger’s headrest, and came to rest in the headliner.
Siderio’s gun: Taurus, 9MM, semi-automatic handgun, equipped with a laser, was recovered from the scene. The gun is in stolen status. The firearm was loaded with one (1) round in the chamber and five (5) rounds in the magazine.
