John Atterberry, who has worked with the Spice Girls, Jessica Simpson and others, died at Cedars-Sinai Medical Center, spokeswoman Simi Singer said.

The 40-year-old executive was shot in the face and upper body as he drove his Mercedes-Benz during Friday’s random attack near Vine Street and Sunset Boulevard.

Atterberry was the only seriously injured victim of 26-year-old Tyler Brehm, who police say fired nearly 20 bullets in the air and at cars as he screamed that he wanted to die. He was killed by police minutes later.

Brehm’s ex-girlfriend has said she and Brehm had recently broken up. But police say they’re still looking for a motive for the attack.

Brehm walked down the middle of Sunset, firing on motorists with no clear target and injuring three of them before two police officers who just happened to be in the area — an off-duty motorcycle officer working movie set security and an LAPD detective — shot and killed him, authorities said.

In amateur video taken at the shooting scene, the gunman appeared to have short hair and wore jeans and a white tank top. He paced back and forth near the busy intersection with Vine, firing from what appeared to be a .40 caliber handgun, police said.

The officers ordered the suspect to stop and drop his weapon. He was shot when he pointed his weapon at the officers, police said.
