(NewsNation) — Los Angeles police have arrested four suspects, ranging in age from 18 to 22, in the fatal shooting of “General Hospital” actor Johnny Wactor.

Three face murder charges, while the fourth was booked as an accessory.

A news release from the LAPD states officers conducted search warrants that led to the arrests early Thursday morning and recovered additional evidence. No further details have been shared about the arrests or the evidence.

Wactor was shot May 25 during an attempted theft of a catalytic converter in Los Angeles. Police said the 37-year-old had left work at a rooftop bar with a coworker when he saw three men who had hoisted his car. Police said one of them fired at him without provocation and killed him.

Wactor was reportedly shielding his coworker from the gunfire.

Wactor, 37, appeared as Brando Corbin in 164 episodes of the popular soap opera between 2020 and 2022. He also appeared in other shows such as “Westworld” and “Criminal Minds.” His agent, David Shaul, said just after Wactor’s death that he “always kept his chin up and kept striving for the best he could be.”

At a news conference earlier in the week, his mother described the feeling of losing him.

“Grief is my constant companion,” Scarlett Wactor said. “I can’t wish him happy birthday on Aug. 31 — he would have been 38. I can’t ask if he’s coming home for Christmas. I can’t ask how his day went.”
