Hochman said the victims’ families have spent more than 15 years waiting for justice.

“These were vicious and callous murders that we believe came at the behest of Mr. Wall, who thought killing two people would end his legal problems,” Hochman said.

Wall was extradited from Montenegro, where authorities claim he had been living after fleeing during the investigation.

He made an initial court appearance Monday, but his arraignment was postponed until July 1 at the Foltz Criminal Justice Center in downtown Los Angeles.

If convicted, Wall faces a potential sentence of life in prison.
