Who is Aaron Michael Cooney?

Cooney was taken into the custody without incident and was transported to the Clark County Detention Centre where he was booked for open murder. He has since been charged with an additional count of murder in the first degree with the use of a deadly weapon where the victim is an older person.

According to the police, Cooney reportedly Aaron, “That’s not our mom anyways. We need a new one,” reports Las Vegas Review Journal. Also, when he asked Cooney where their mother was before finding her in the pool, he allegedly replied, “I stabbed her last night. She’s gone.” However, as per reports, he told police that his mother died three days earlier and said, “You guys know I’m not a murderer.”

On Wednesday, May 17, his first formally-designated initial appearance took place where he asserted his Fifth and Sixth Amendment rights, and medical privacy rights.
