Nearly two years later the murder trial of Jennifer Fiero has begun with the defense trying to prove that it was all an accident.
Juan Perez is on trial for the death of 17 year old Jennifer Fiero.
The incident took place early morning on May 15, 2011 on Hamilton Avenue in El Centro.
The prosecution trying to prove that Perez intentionally ran over Fiero after a party the previous night.
Perez was there to pick up his girlfriend Renata Martinez.
"You’re going to see the injuries with the tire marks on her leg and on her arms and ultimately one of the tires crushes her skull and kills her," Prosecutor Jeffrey Brooker said.
The defense trying to prove it wasn’t intentional. Perez’s lawyer Steven House says his client has never been in a fight and has no criminal record.
"Is this the type of person that is likely to do that based on the way that they live their life in the past," House said.
Arturo Ortega who attended the party says he witnessed perez and his two friends with a machete, a baseball bat and a knife.
"All they were doing was swinging it at the top of their heads like this saying eastside eastside," Ortega said.
House says a fight broke out that morning between fiero and martinez which was the beginning of a tragic end.
"She still had her whole life ahead of her. She was a good student. She was a good sister, daughter, friend," Fiero's sister Cynthia Fiero said.
The prosecution will continue to call his witnesses this week.
