Ex-Philadelphia Police Officer Pleads Guilty to Murder of 12-Year-Old Thomas Siderio

Former Philadelphia police officer Edsaul Mendoza pleaded guilty on Wednesday to third-degree murder and possession of an instrument of crime for the March 2022 shooting that killed 12-year-old Thomas "T.J." Siderio. Prosecutors said Siderio, who was unarmed and on the ground when Mendoza fatally shot him, became the youngest person ever killed in a shooting by a Philadelphia police officer.

The shooting occurred after Mendoza and other plainclothes officers were investigating a report of a teenager with a gun. Siderio fired shots at the officers' unmarked car, but prosecutors said he was unarmed and on the ground when Mendoza shot him. Mendoza, a five-year veteran of the force, was fired from the police department for failing to follow protocols for the use of deadly force.

Why this matters: The case has been seen as demonstrating the need for rigorous oversight of the police department. Siderio's family has sued Mendoza and the city for damages, alleging his death was the result of "an abysmal systemic policy failure" within the police department.

As part of a plea deal with the Philadelphia District Attorney's Office, Mendoza pleaded guilty to third-degree murder and possession of an instrument of crime. He is facing a recommended sentence of 7.5 to 40 years in prison. The Siderio family expressed disappointment with the plea deal, stating that Mendoza should have been accused of first-degree murder.

Prosecutors acknowledged that not all family members were happy with the plea deal but said they did take their input into consideration. "Justice must be evenhanded," the Philadelphia District Attorney's Office stated. "Everyone must be accountable under the law."

While the plea cannot bring T.J. back, it signals the close of a painful chapter for his family and the community. The Philadelphia Police Oversight Commission remains committed to overseeing police practices and ensuring officers are held accountable. The case demonstrates the critical need for rigorous oversight and reform in law enforcement, setting a crucial precedent for future cases involving police misconduct.
