Albert Posey, 57, was fatally shot on December 28, 2020, while driving on the Lower West Side of Chicago. The shooting happened about 4 a.m. in the 2300 block of South Wood Street. Posey was driving south when someone in a gold-colored SUV opened fire, striking him multiple times in the back. He was taken to Stroger Hospital and pronounced dead; the Cook County medical examiner ruled the death a homicide and Area Four detectives investigated.

Prosecutors say Angel Avelar, 22, drove a Chevy Tahoe belonging to his father with two passengers who were spray-painting gang graffiti nearby. As Posey drove past, he reportedly stopped, briefly got out, then returned to his vehicle. Avelar allegedly moved the Tahoe closer and one of the passengers opened fire. Police later recovered gunshot residue in the back passenger area, videos of the tagging on Avelar’s phone, and GPS data placing the phone at the scene. A 19-year-old passenger has also been charged; because he was a minor at the time, his case may be handled in juvenile court.

Avelar was on bail for a felony gun charge at the time and had been released from electronic monitoring after completing probation for a prior gun possession case; prosecutors describe him as a public safety threat and he is detained. Does anyone have information about Posey or the events that night that could help investigators?
