Custody Disptue- TRO didnt work.

Police say the motive for the attack appears to be a custody dispute.

One of the victims was the rifleman's 29-year-old live-in girlfriend. She was shot in the elbow and listed in stable condition. The woman's son, 9, attended the festival and was unharmed. It was unclear whether the rifleman was the boy's father, Eisenman said.

The two other victims were a 45-year-old man who was shot in the leg and a 43-year-old man who was shot in the chest. Both are in stable condition.

Eisenman said the gunman used a semiautomatic rifle.

After the initial shots, the assailant was subdued by bystanders, one of whom was an off-duty police officer, Eisenman said.

Witnesses told KABC-TV Channel 7 that the rifleman roamed around the festival before pulling the weapon out of a tennis bag. He then seemed to randomly open fire, witnesses said.

"We have a parent who apparently has a restraining order, and he came in, kissed his son and pulled an assault rifle out and shot three people," parent Martinique Williams told Channel 7.
