He discovered his parents shot inside their master bedroom Friday night, Joseph McManus told Las Vegas police.
But homicide detectives immediately noticed McManus, 43, had blood on his shirt and that his alibi — that he was gambling at a nearby gas station — didn’t add up, according to a police report released Monday.
The report said McManus called police shortly before
9 p.m. and said his father, James McManus, 70, and mother, Alma McManus, 67, were shot.
James McManus was dead when officers arrived at the home in the 4300 block of Cottontail Lane, near Flamingo and Pecos roads. Alma McManuswas taken to Sunrise Hospital and Medical Center, where she died.
Detectives questioned Joseph McManus. He initially denied any involvement, the report said. He told investigators he gambled at a nearby gas station starting at 8 p.m. and returned to the home two hours later.
But he called police reporting his parents were shot at 9 p.m., the report said.
He then changed his story and admitted to detectives he had argued with his parents, the report said.
He said that his father took out a gun and the two fought over the weapon when it accidentally discharged, striking the elder McManus, the report said.
Joseph McManus also told detectives that after his father was shot, his mother attacked him, which led to another struggle over the gun that left her fatally wounded.
Joseph McManus called 911 after the shooting, he told investigators. When he returned to his parents’ home, he did not expect his mother to be alive, the report said.
Joseph McManus remains in the Clark County Detention Center without bail on two charges of murder with a deadly weapon on a person older than 60.
