Jorge Ocampo, 21, surrendered late Friday night after the violent collision at Cabrillo Park Drive and Fruit Street. Authorities say Ocampo's family members were at his side as he turned himself in.
Santa Ana police say Ocampo faces charges of vehicular manslaughter, felony hit-and-run and driving without a license.
Investigators say Ocampo ran a stop sign in a black Audi at about 11 a.m. He broadsided a Nissan minivan, killing 50-year-old Jose Luna and 53-year-old Alejandro Bravo. Bravo was declared dead at the scene, and Luna died at an area hospital.
Witnesses say they saw Ocampo get out of the Audi to check on the passengers in the minivan. He then pulled out his cellphone, but police say he didn't dial 911 for help. Instead, he called a friend to pick him up, leaving the two victims to die.
Santa Ana police say Ocampo then fled into a nearby condo complex after the crash and then vanished. Police earlier said there was also another man in the car with Ocampo, but after interviewing witnesses, officers determined that there was only one suspect in the vehicle.
Friday night, family and friends gathered to remember the two men.
"I'm going to miss him. I don't even have words that can express how I feel inside right now," said Bravo's nephew, Bryan Ledesma.
Luna was a longtime groundskeeper at the Redwoods Apartments in Santa Ana. He and Bravo were both grandfathers, good friends and neighbors. They were on their way to buy food for their complex's barbeque at the time of the crash.
Investigators do not know who Ocampo called after the accident. Authorities say that person could face charges for possibly helping Ocampo leave the scene of the crash.
