CAHOKIA — A 57-year-old Cahokia man was charged Saturday evening in connection with killing his wife and shooting his son.

Ovie Sumpter, of 502 Cooper Drive, was charged with first-degree murder, attempted first-degree murder and aggravated battery with a firearm.

He is accused of shooting and killing his wife of several years -- 53-year-old Tina M. Sumpter, also of 502 Cooper Drive -- and shooting his 23-year-old son Jason J. Sumpter, who survived, but is hospitalized.

Tina Sumpter died as a result of the gunshot wound to her head. She was pronounced dead at the scene, St. Clair County Coroner Rick Stone said.

Cahokia police found the gun they believed was used in the shootings inside the Cooper Drive residence.

Ovie Sumpter fled from the scene, but was later captured by Pevely, Mo., police. Cahokia Police Lt. Dennis Plew said police believe he was headed for Farmington, Mo.

He is currently being held in Pevely in lieu of $3 million bail. He is expected to be extradited Sunday or Monday.

Cahokia police were called to the Sumpter home shortly after 5 a.m. to investigate a shooting in which the caller reported that the victim needed medical attention.

When police officers arrived at 5:08 a.m., they found one victim, Jason Sumpter, at a neighbor's house.

Asked about a possible motive for the murder and attempted murder, Plew said police are still investigating.

Jason Sumpter told police his father left the scene in a red Dodge pickup and he thought he might be headed to Farmington, Mo.

Cahokia Police put out a notice at 5:45 a.m. with the description of the suspect and an officer in Pevely spotted the suspect.

"Initially the suspect did not stop for the officer, but the officer eventually got him stopped. The suspect identified himself as the individual we were looking for," Cahokia Police Chief James Jones said.

"If it wasn't for the outstanding police work by this officer we could possibly be still looking for our suspect," Jones said.
