A Chicago man who served 17 years in prison for murder before being cleared of the crime and released has been shot and killed almost three years after leaving prison.

Chicago police spokesman Anthony Guglielmi (gooh-YEHL'-meeh) says 40-year-old Alprentiss Nash was killed Tuesday after arguing with his attacker.

He says police are questioning a person of interest.

Nash was convicted in the 1995 murder of Leon Stroud on Chicago's South Side, based on witness testimony. In 1997, he was sentenced to 80 years in prison.

He was released in August 2012 after DNA tests on a ski mask worn by the killer matched the genetic profile of another man.

Nash received a settlement of more than $200,000 from the state. A federal civil rights case is pending.
