John Christopher Atterberry, 40

John Atterberry, a 40-year-old black man, died Monday, Dec. 12, three days after he was shot near Vine Street, south of Sunset Boulevard in Hollywood, according to Los Angeles County coroner's records.

Atterberry, a music and real estate executive, was driving the afternoon of Dec. 9 when he was shot three times in the face and neck by a gunman, later identified by authorities as Tyler Brehm, a 26-year-old white man.

Brehm began firing a .40-caliber handgun at motorists, police said, hitting Atterberry's silver Mercedes-Benz coupe. The gunman fired about 20 rounds before he was killed by Los Angeles police.

Brehm reportedly had broken up with his longtime girlfriend days before the rampage. His ex-girlfriend, Alicia Alligood, told KTLA-TV Channel 5 that he seemed "stressed out" after the breakup and may have been taking prescription drugs.

According to a biography posted on the Facebook page of the event promotions company GridLock Group, where Atterberry served as senior partner and chief financial officer, he was a Los Angeles native who got his start working in artists and repertoire for Tabu Records.

He worked in marketing in the fashion industry, then returned to the music industry, where he became the vice president of Death Row Records. The label was home to some of the biggest acts in West Coast hip hop, including Tupac Shakur, Dr. Dre and Snoop Dogg.

Atterberry later founded Los Angeles-based music publishing company Infusion Music Group, where he worked on albums for Christina Aguilera, Michael Jackson, Brandy, the Spice Girls and Jessica Simpson.
