The scene in Colma was hard to look at Memorial Day morning -- a green Mustang split in two on Hillside Boulevard after it rear-ended a Honda. Three people were ejected from the Mustang and died.
A memorial has been set up at the scene with candles, flowers and the names of the three victims. They are identified as 23-year-old Rosa Falla, 21-year-old Jonathan Mouton and 22-year-old Ruvin Vazquez -- all from Daly City. Friends and family of Mouton left tools at the memorial; they said he was a mechanic, always willing to help.
"If you needed anything he was there. Johnny was always willing to participate in something or help someone. Real nice guy," Jonathan Mouton's friend Joe Cordero said.
Police say Diaz was speeding in the Mustang and believe alcohol was a factor in the crash with evidence found in the car. He was the only survivor from the Mustang.
"He was like 'baby, baby, baby.' I guess he was trying to get the girl's attention to see if she was alive and then I don't know the girl didn't respond back so he just went under where that broken thing is and he just went under and walked down and he didn't come back up," witness Jesus Haro said.
Christina Falla says she's sure Diaz feels the pain her family is going through. She and Rosa Falla were cousins but were raised more like sisters since they were little girls.
"Partners in crime; one of my best friends for sure," she said.
Tuesday morning, police revealed new details about their investigation, saying Diaz fled the scene to a Daly City home, believed to be related to his girlfriend Falla. Police say they collected evidence from the crash scene at the home. However they say they don't know where Diaz went after that, before turning himself into police six hours after the crash.
Colma police said they expect the toxicology reports to take several weeks.
