A 30-year-old man will be charged with open murder after police say he shot 18-year-old Grady Manns Jr. in the chest early Thursday morning, May 12.

Terrence Shelby Jr. will also charged with felony illegal firearm possession, according to a news release from the Berrien County Prosecutor’s Office. He faces a life sentence for the open murder charge and two years for the firearm charge.

Shelby and Manns were arguing at Shelby’s home in the 100 block of East Empire Avenue around midnight Thursday when he shot Manns in the chest, the prosecutor’s office said. A neighbor reported hearing a gunshot around midnight near the alley behind the Empire Avenue home.

Manns’ body was found in a field about a block from the house after a bus driver spotted him and called 911 at 7:15 a.m. Thursday. An autopsy confirmed that Manns died of a single gunshot wound to the chest.

Manns was a junior at Benton Harbor High School. He recently became a father.

Shelby is expected to be arraigned on Monday, May 16.
