According to court documents, Bethany Hamlin was vacuuming in her grandfather's house in the 18500 block of Normandy Terrace SW when she was suddenly attacked by her friend and her grandfather's caretaker, 23-year-old Shane Chamberlain.
Chamberlain is accused of hitting Hamlin a dozen times with a metal crowbar in the Jan. 25 attack. She later said the attack was completely unexpected and unprovoked.
According to court documents, Hamlin was able to defend herself with a chair and escape to a neighbor's house, where she collapsed.
Next, Chamberlain found a revolver kept in the home and shot 96-year-old Philip Hamlin, killing him as he rested in the family room, according to the documents.
Chamberlain reportedly called 911 and confessed to the murder immediately.
According to court documents, Chamberlain was having marital problems and told a 911 dispatcher that's why he "broke."
Chamberlain, who has no known criminal history, is being held on $2 million bail.
In his court appearance Monday, he appeared somberly before the judge. His eyes were mostly down and he never spoke.
He is due back in court Feb. 24.
