The lawsuit names the Chicago Police Department and the officers involved in the shooting. The officers have not been publicly identified. However, three officers have been relieved of their duties in connection with the shooting.
The lawsuit alleges wrongful death and that Paul O'Neal's constitutional rights were violated, said family attorney Michael Oppenheimer.
"If he was in a stolen vehicle and he committed a crime, that is for the court system to decide what his sentence should be, not the police officers executing this boy.
Shooting him in the back," said family spokesman Ja'Mal Green.
NO VIDEO OF THE SHOOTING
Green called on the immediate release of video of the shooting, but said that O'Neal's family is distraught and not interested in viewing the video.
However, the body cam worn by the officer who fired the fatal shot did not capture the shooting. Multiple cameras captured the night of the shooting, however, none captured the shooting, said Chicago police Supt. Eddie Johnson.
"There's a lot of video footage of it, but not the actual encounter. That part is not captured on video," Johnson said.
The officers in question received their body cams within the previous 8-10 days, said Frank Giancamilli, a CPD spokesman. Police are unsure as to the exact reason why the footage was not recorded on the officer's camera.
OFFICERS RESPONDING TO STOLEN CAR REPORT
Oppenheimer and Green held a press conference Monday, on behalf of the family, at the scene of the shooting, which occurred Thursday near East 74th Street and South Merrill Avenue in the South Shore neighborhood.
The officers involved in the shooting were responding to a call about a stolen Jaguar from southwest suburban Bolingbrook. O'Neal was driving the vehicle, which crashed into a police cruiser and then sideswiped another before two officers started shooting from inside their car. A third officer got out of their car and fired, what police believe, was the fatal shot.
Johnson said he believes the officers may have violated department policy, but did not specify.
The city's Independent Police Review Authority is investigating.
