SANTA MONICA, Calif. (AP) - Police in Southern California who are investigating why a heavily armed gunman plotted a rampage that killed four people and wounded several others are focused on how the violence began.
What started as domestic violence Friday led to a chaotic street shooting rampage and ended less than 15 minutes later in the Santa Monica College library where the gunman was killed by police.
An official briefed on the probe says investigators are looking at family connections to find a motive because the killer's father and brother were the first victims.
Police Chief Jacqueline Seabrooks says the killer, who died a day shy of his 24th birthday, was connected to the home that went up in flames after the first shootings. She refused to elaborate or name the suspect because a surviving family member was out of the country and couldn't immediately be notified.
At a Saturday afternoon news conference next to weapons and ammo found at multiple crime scenes, Seabrooks said the "cowardly murderer" planned the attack and was capable of firing 1,300 rounds.
The killer had a run-in with police seven years ago, but Seabrooks wouldn't offer more details because he was a juvenile at the time.
