Edsaul Mendoza, 26, was one of four plainclothes officers inside an unmarked police car on the evening of March 1 when they pulled up to 12-year-old Thomas “TJ” Siderio and a 17-year-old identified as “NK,” Krasner said. TJ then “likely” fired at the vehicle and a bullet entered the rear window, Krasner said.
Three of the officers took cover, but Mendoza engaged in a “tactically unsound” foot chase of the boy and shot at him three times, Krasner said.
During the chase, TJ tossed aside the gun, Krasner said. Even so, Mendoza twice fired at the boy after the gun was discarded, he said. Mendoza fired the fatal shot from a half-car length away when the 12-year-old was lying face down on the ground, Krasner said.
Immediately afterward, Mendoza directed another officer to the spot where the boy had thrown the gun, which was found 40 feet away, the DA said.
“Thus when Officer Mendoza fired the third and fatal shot, he knew the 12-year-old, 5-foot tall, 111-pound Thomas Siderio no longer had a gun and no ability to harm him,” Krasner said.
Mendoza was charged in the presentment with first-degree murder, third-degree murder, voluntary manslaughter and possession of an instrument of crime with intent to use it criminally, said Krasner.
He was taken into custody Monday morning and is being held without bail, Krasner said. A preliminary hearing is set for May 16, according to court records.
The Philadelphia Fraternal Order of Police said it will represent Mendoza in the case.
“The accused constitutional officer, like every other citizen, is entitled to due process and we are confident that our judicial system will protect this officer’s right to a fair trial,” Philadelphia FOP Lodge #5 President John McNesby said in a statement.
Grand jury questions decision to stop boys
“Based off of the evidence that I reviewed, it was clear that the use of force policy was violated,” Outlaw said at the time. “I will tell you that all use of force has to be proportionate to the resistance they’re trying to overcome. I will also tell you that our policy clearly states that excessive force will not be tolerated.”
The officers were on patrol as part of a stolen firearm investigation connected to a third person, and the officers believed the 17-year-old was tangentially connected to that investigation, the document states. However, the purported reason for the stop differed among the officers, the two officers said they stopped the boys for a traffic violation, the document states.
The officers drove the unmarked car with tinted windows up to the boys and then put the emergency lights on. At about the same time, the gunshot went off and struck the rear window of the vehicle, according to the presentment.
The plainclothes officers did not announce themselves as police officers, the document states. Philadelphia police policy states that plainclothes detectives “will not routinely make traffic stops” unless there is a clear danger, according to the presentment.
After the shooting, Mendoza chased after the 12-year-old, and the other three officers did not see what happened at the end of the street, the document states.
The 9 mm semi-automatic handgun equipped with a laser was recovered from the scene, according to a March police statement. The gun was reported stolen and was loaded with one round in the chamber and five rounds in the magazine. The 17-year-old boy who was at the scene was not hurt, authorities said. It was questioned and released pending further investigation.
One of the officers was injured in the eye by glass when the car was shot, the police statement said. The bullet went through the passenger side rear window and through the headrest of the front passenger’s seat where another officer sat, the statement said.
