Police are searching for two people believed to be connected to a fatal shooting of a south suburban man early Saturday in northwest Indiana.

Officers were called at 12:07 a.m. for reports of a gunshot victim in the 5400 block of West 25th Avenue, according to a statement from Gary police. They arrived to find a man inside a business with a gunshot wound.

Marcel Harris, 29, showed “no signs of life” when officers arrived, and he was pronounced dead at the scene at 12:55 a.m., according to police and the Lake County coroner’s office. He was a resident of Sauk Village.

An autopsy found he died of a gunshot wound and his death was ruled a homicide, the coroner’s office said.

Authorities have released photos of two people who may be connected to the shooting. The male and female suspects were last seen heading west on I-80/94 in a black SUV.

Anyone with information on the shooting is asked to call Det. Kristopher Adams of the Lake County/Gary Metro Homicide Unit at (219) 755-3855; or the crime tip line at (866) CRIME-GP.
