Wyoming murder suspect Brady Oestrike held 18 year old Brooke Slocum captive for several days before eventually killing her.
Wyoming Police Chief James Carmody told a news conference Slocumb's boyfriend 25 year old Charlie Oppeneer was beheaded.
Carmody said the events that led to the killings of Slocum and Charles Oppeneer and the suicide of Oestrike began with an arrangement made on Craigslist to meet for sex between Oestrike and Slocum with Oppeneer present.
Wyoming Police Capt. Kim Koster said a motive has not been determined in the murders and may never be known.
