Accused Cemetery Killer Charged In Cunningham Slaying: Banning

BANNING, CA — A man who was charged in the Aug. 30 shooting attack at a Banning cemetery that left three people dead is now accused in another killing, the Banning Police Department announced Monday.

The news comes following the Sept. 4 announcement by Banning police that William Arnold Armendariz III, 23, had been arrested along with three others in connection with the slayings at San Gorgonio Memorial Park Cemetery.

On Monday, the department said Armendariz was also responsible for the July 1, 2018 shooting death of Bradley Seth Cunningham. The 21-year-old man was found by police with several gunshot wounds around 10 p.m. that night on East Barbour Street in Banning. Despite life-saving measures, Cunningham died from his injuries. According to police, another person was also fired on during the shooting attack.

Armendariz, who has already been charged with three counts of murder in the cemetery killings, is now facing another murder charge, according to police.

Like the cemetery killings, Armendariz was not alone in the 2018 slaying, according to police. Brandon Daniel Hylkema, 43, was arrested Friday in Indio and booked on suspicion of murder in connection with Cunningham's death. Also arrested in the case was Jovanny Daniel Martinez, 22. Martinez was taken into custody on Oct. 8 on Ramsey Street in Banning and booked on suspicion of murder.

Cunningham's mother has pleaded with the public to help find her son's killer(s). She even took out a billboard on Ramsey Street that featured a photo of her son and the words, "Do you know who murdered me?"

Police did not disclose whether the victims in the Aug. 30 cemetery shootings and Cunningham had any connection.
