Prosecutors say 22-year-old Shane Ryan Chamberlain was a live-in caretaker for 96-year-old Philip Hamlin. On Saturday afternoon, Chamberlain picked up a crow bar and began beating Hamlin's daughter, Bethany, as she vacuumed the house, according to court papers.
Bethany attempted to fight back against the unprovoked attack with a metal chair, but police say Chamberlain was still able to hit her 12 times on the head, neck and arms.
During a lull in the attack, Bethany was able to escape and run to a neighbor's house for help.
When he realized Bethany was gone, prosecutors say Chamberlain found a handgun Hamlin kept in the house and shot the elderly man twice as he rested on a couch.
Chamberlain then called 911 and told dispatchers that he had just murdered someone. Asked why he had done it, Chamberlain told the dispatcher he had "broke," according to charging papers.
Police arrived moments later and found Hamlin dead on a couch in the family room. He had been shot in the face. They also found a .38 caliber Smith & Wesson revolver and a bloody crowbar just outside of the house.
Chamberlain was charged on Tuesday with first degree murder with a firearm enhancement. He was also charged with first degree assault with a deadly weapon.
His bail was set at $2 million.
Prosecutors say Chamberlain has no known criminal history.
