A personal trainer has been arrested in connection with the murder of a former pro hockey player and a criminal justice advocate in a California condo, police said.

Jamon Rayon Buggs, 44, was arrested Thursday on suspicion of murder in the deaths of Darren Partch, 38, and Wendi Miller, 48, who were found dead by Partch’s roommate in Newport Beach late Sunday, KTLA reports.

Buggs was already in police custody; he was arrested Monday in connection with a series of attempted home burglaries in Irvine.

It’s unclear how he was connected to the slayings, but murder charges are expected to be filed against him Friday, Newport Beach police said. He’s being held on $1,000,000 bond, KTLA reports.

The pair was last seen near the Sandpiper Bar in Laguna Beach on Saturday afternoon, friends told the station. A cause of death has not been released, but investigators have said no sign of forced entry was found.

Miller’s relatives began posting on social media when she didn’t return home after planning to give Partch a ride, since they lived just a few blocks away from each other, according to the station. The exact relationship between Partch and Miller is unclear.

Partch was a former minor-league hockey player who played 13 seasons, ending his career in 2006 with the San Diego Gulls, according to the Orange County Register. Miller, a mother of two, was the founder of Wings for Justice, a nonprofit advocacy group focused on the family court system.

Buggs, according to his Facebook profile, is a personal trainer who previously worked at Equinox in Huntington Beach. He has also studied at Arizona Western College and is originally from Compton.
