Atterberry is a longtime recording industry manager and promoter and has been involved with acts like the Spice Girls and Jessica Simpson.

He most recently was senior partner and chief financial officer at the GridLock Group, an event promotions company. According to his bio on the firm's Facebook page, the Los Angeles native got his start in A&R at Tabu Records. He then did a stint in fashion, working for Cross Colours and Karl Kani as head of marketing and promotions, before returning to the music business as vp at Death Row Records, home to such acts as Tupac Shukar, Dr. Dre and Snoop Dogg.

Atterberry later created Mergela Records and Consulting, where he repped Rodney Jerkins and Chris Tucker and produced label deals with Def Jam, Arista, Ruthless Records and Sony, and also founded music publishing company Infusion Music Group, where he worked with the Spice Girls and Simpson, among others.

He joined GridLock in 2007 and concurrently served as chief financial officer of the VIP Group, a Hollywood-based real estate brokerage firm.

VIDEO: Gunman Opens Fire Near Hollywood's ArcLight Theater

The gunman, identified as 26-year-old Tyler Brehm by the Los Angeles County Coroner's office, randomly opened fire at approximately 10:19 a.m. Friday near the ArcLight Cinemas. The suspect allegedly fired between nine and 12 shots before being killed by police, according to reports. When he ran out of bullets, the gunman allegedly pulled out a knife, yelling, "Kill me" and "I want to be killed."

In what the Los Angeles Police Department called a "random shooting," witnesses enlisted the help of two police officers who were working on a nearby movie set after seeing a man open fire in the street. The man walked northbound on Vine with a gun in the air and when cars began driving by, lowered his gun and fired at them.

One of those vehicles which was shot at was a photo editor, who was on his way to work from his North Hollywood home when the gunman fired at his black truck, which was captured on video.

On Saturday, new information released about the shooter showed he broke up with his girlfriend of four years, Alicia Alligood, this month. She said that their split may have triggered Brehm's shooting rampage.

She also said that he had been very stressed lately and began taking drugs given to him by an unnamed pharmaceutical salesperson.

Alligood said he was a "humanitarian" who was "extremely motivated to change the world for the better."
