The live-in boyfriend of an Iowa City woman who was found dead earlier this week is now charged with first-degree murder. Johnson County Sheriff’s deputies were called to the home of 34-year-old Sarah McKay at 9:30 Sunday night.

McKay was found dead in her bedroom. Her live-in boyfriend, 26-year-old Eric Osborn, admitted hitting her with a baseball bat and strangling her to death. He then tried to kill himself by cutting his wrists and neck. Johnson County Attorney Janet Lyness says Osborn’s criminal history includes several drug-related charges and a drunk driving conviction one year ago.

“I would say an OWI is not going to give any indication there’s going to be this kind of violence in the future,” Lyness said. Osborn told investigators he had no idea why he killed McKay, but said it happened early Sunday morning after a night of drinking and taking drugs. He blacked out in his truck after trying to kill himself and called his mother when he awoke Sunday night.
