SOUTHFIELD (WWJ/AP) – Family members say they have taken a man off life support who had been critically wounded while trying to help robbery victims in Detroit.

Thursday night, 61-year-old Calvin Robinson was removed from life support after spending six months at a Southfield hospital. His wife, Sharon, said family members “kept hoping and hoping” but doctors said there was nothing else they could do.

Robinson was shot in the head Aug. 12 after trying to help two women being mugged near downtown’s Renaissance Center. According to police, Robinson was driving down Atwater Street near St. Antoine Street when he spotted the crime and decided to intervene. When Robinson approached to try to assist the woman, police say two men attacked him and started shooting.

The incident occurred while the Rib and Soul Festival was taking place at Hart Plaza. Robinson was the only one injured.

Robinson was listed in temporary serious condition after the incident. Sharon Robinson told WXYZ that at first, her husband could talk a little bit but he never fully  recovered like they hoped.

No arrests have been made, and police are still seeking the public’s help in solving the case.

Shortly after the shooting took place, a group of eight black males and one black female was recorded on surveillance video walking east on Jefferson Avenue and crossing the entrance ramp for the Detroit Windsor Tunnel.

Three of the group’s most noticeable members are:

— A black male wearing a red shirt, dark pants and red shoes. He was carrying what appeared to be a long blue light saber or glow stick that blinks.
— A black male wearing a white t-shirt, white hat and tan pants.
— A black male with no shirt and blue jeans.

Police say that because the shooting took place during a festival, there are believed to have been many witnesses to the robbery and the shooting.

Anyone with information is asked to contact Crime Stoppers anonymously at 1-800-SPEAK-UP, online at, or by texting “CSM” and your tip information to CRIMES (274637).
