LOUISVILLE, Ky. (WDRB) -- A Louisville man has been charged with murder after a man was found strangled in a room at the Red Roof Inn on Friday. 

Although he had been in police custody for several days, 40-year-old William Mattingly wasn't booked into Metro Corrections until around 8 p.m. Monday. 

Early on Nov. 13 Police found 28-year-old Thomas Grismer dead in his hotel room, and police say Mattingly was trying to choke a second victim when officers arrived. 

According to police, Mattingly had "placed a second victim in a chokehold which was not released until LMPD officers intervened." 

Police believe Grismer and the Mattingly were staying at the hotel with a group of friends.

"I believe they were friends and something went really bad and terrible to the point that this individual lost his life,” said LMPD spokesman Dwight Mitchell. “I think there were other people in the room, but I’m not sure who was staying where, but there was more than one person in the room." 

On Tuesday Mattingly pleaded not guilty to murder and attempted murder. Mattingly is being held on a $750,000 cash bond, and is due back in court on Nov. 25.
