More than two months after a man was charged with murdering his mom, authorities testified that he admitted to shooting her 17 times before stabbing an elementary school teacher to death.

At a probable cause hearing Tuesday, Cobb police detective Jonathan Bradley said Justin Hess, 31, allegedly killed his mom Carol Ann Hess, 61, after she didn’t understand his beliefs, Channel 2 Action News reported.

“He believed there was something consistent with a New World Order that caused him a lot of stress,” Bradley said. “He believed he was under surveillance, that sort of thing.”

According to police, On Dec. 17, Hess told police he shot his mom 17 times inside their apartment at their Marietta townhouse because he snapped, Channel 2 reported. Bradley testified Hess went through a gun’s magazine of 20 before reloading it with a magazine of 30.

Bradley said when neighbors became suspicious of Hess, he began speaking in a British accent, Channel 2 reported.

He then drove to Extra Space Storage on Roswell Road in Sandy Springs, allegedly stabbed beloved music and drama teacher William Haynes, 53, and drove off in Haynes' red Audi S5.

Bradley said Hess told them he stabbed Haynes because he thought he needed another car, Channel 2 reported. An AR-15 and a samurai sword were later found in Hess’ car trunk.

A SWAT Team arrested Hess at his home the morning after the deadly shooting and stabbing.
