Last Tuesday, Philadelphia police officers shot 12-year-old Thomas "TJ" Siderio in the back, cutting his young life far too short.
There is still much that we don't know about the events surrounding TJ's death.
According to police, TJ was with a 17-year-old friend when four officers in an unmarked vehicle approached them. The officers said they heard gunfire; a rear window shattered on their car. Two officers chased TJ — who police say was holding a 9 mm semiautomatic handgun — and fatally shot him in the back.
