The driver parked outside a hotel and surveyed the leisurely summer scene at the Venice Beach boardwalk: Hundreds of people were sitting at cafes, walking along the seashore or shopping at vendors selling jewelry or art.
Then, according to surveillance video, the man got into a large, black car, steered around a vehicle barrier and accelerated mercilessly through the crowd, hitting one person after another as bystanders tried desperately to get out of the way.
Saturday’s hit-and-run killed an Italian woman on her honeymoon and hurt 11 others who only a moment earlier had been enjoying an afternoon near the beach at the height of vacation season.
A couple of hours later, authorities arrested a man on suspicion of murder after he walked into a police station in neighboring Santa Monica and said he was involved.
Nathan Louis Campbell, 38, of LA, remained jailed Sunday on $1 million bail.
Police declined to discuss a motive, but Deputy Chief Kirk Albanese said there was no indication that the attack was a terrorist act or that anyone else was involved.
By the time it was over, the driver had covered about a quarter of a mile along the boardwalk before fleeing. The entire incident was over in minutes.
On Sunday, the boardwalk featured the typical summer crowd, people on roller blades, beach cruisers, performers and regular vendors.
The Italian woman who was killed was identified as Alice Gruppioni, 32. Her family in Bologna told the Italian news agency LaPresse that she had been on her honeymoon after a July 20 wedding.
The family declined to speak to The Associated Press on Sunday.
Another person was critically injured. Two others were taken to hospitals in serious condition. Eight suffered less-serious injuries, police said.
According to security video and witness accounts, the driver parked next to the Cadillac Hotel and twice walked out to the boardwalk before getting into the Dodge Avenger.
He carefully maneuvered between a storefront and metal poles that had been erected to prevent anyone from driving onto the boardwalk.
Then he stepped on the accelerator and plunged into the crowd.
The driver knocked over two mannequins and an ATM and started hitting people, swerving from side to side and often running straight into victims.
Video showed the car struck at least three vendors. Two women who appeared to be in their 60s also were hit.
