Columbus police went twice Friday morning to the Silver Oak Drive home where Classie Victoria Mixson lived on the Southeast Side.

The first time was to respond to a disturbance between Mixson, 32, and her boyfriend, Keith Marshall, 28. The second time, police said, was after Marshall fatally shot Mixson. She was pronounced dead of multiple gunshot wounds outside her home.

In the first incident at 9:13 a.m., after police talked to the pair, Mixson allowed Marshall to enter the residence and remove personal belongings, said Columbus police spokesman Sgt. Rich Weiner.

Weiner said it was unclear whether Marshall lived in the house in the 2500 block of Silver Oak Drive, near the village of Brice.

One of the two police officers who responded to the first call left. The other remained in the area in his cruiser to fill out paperwork.

At 10:10 a.m., the officer still in the area heard Mixson's address again in a police radio report of a woman being shot outside the home. He raced back to the scene and saw Marshall driving away in a maroon pickup truck.

Marshall led police on a brief chase before pulling into the Moors at Countryview, an apartment complex on the 6200 block of Lowridge Drive, about 2 miles from Mixson's home.

There, Weiner said, Marshall jumped from the pickup with a gun in his hand. An officer fired a shot at Marshall but missed, Weiner said.

Marshall ran a short distance away, then turned the gun on himself and fired once, Weiner said. He was taken to OhioHealth Grant Medical Center, where he was listed in critical condition Friday night.

Police said two children, ages 5 and 6, were in the truck with Marshall during the pursuit, but were unharmed. Though the children apparently got into Marshall's truck at the Silver Oak address, Weiner said he did not know whether Marshall is their biological father. Police said the children were later returned to their biological mother.

Mixson was a correction officer at the Franklin Medical Center on Harmon Avenue on the West Side. Marshall had been employed as a correction officer at the state Correctional Reception Center in Orient, Pickaway County, according to a prison official.

Police continue to investigate what led Marshall to shoot his girlfriend, then himself, Weiner said in a statement issued Friday night. Mixson's was the ninth homicide in the city this year.
