Oklahoma City police have made an arrest in the killing of an Oklahoma City bookstore owner.

Kenton Eugene Busby, 42, has been arrested on a murder complaint in the death of Kelly Hays, 66, owner of 30 Penn Books, said police spokeswoman Megan Morgan.

Police on Monday released video captured by an Oklahoma City bus showing a man detectives later identified as Busby, who willingly came to the police department, spoke with detectives and was subsequently arrested, Morgan said.

Hays was found dead September 14 at the bookstore, 3023 N Pennsylvania Ave. The bookstore had been set on fire and Hays had died of sharp force trauma and was found under books, authorities reported.
