A team of biologists with Caltrans discovered Alonso's body Monday night one mile east of a US Forest Service Station in San Juan Capistrano along Ortega Highway in the Cleveland National Forest.
Alonso's cause of death is "undetermined" based on the autopsy, Orange County Sheriff's Lt. Jeff Hallock said Wednesday. Her body showed "no obvious signs of trauma," and toxicology tests were being performed.
Alonso's father Isaac said on Tuesday he is convinced she was murdered, and is hoping for justice.
"I want someone to pay for this. I want the one who did this, I want him to pay for what he did," he said.
Isaac Alonso said he came within a few hundred yards of finding his daughter's body during his own searches.
The night she disappeared, Erica Alonso and her date befriended a couple at the Sutra Lounge Nightclub in Costa Mesa. The group went to Erica Alonso's boyfriend's home in Irvine, where she and her boyfriend got into an argument outside, officials said.
The other couple left about 3:45 a.m. Erica Alonso left the home about 15 minutes later, and there was no trace of her since, Hallock said.
On March 25, Erica Alonso's white 2014 Honda Civic EX was found near Cedarbrook and Redwood in the Glenwood Park neighborhood, which is about a mile from her home, Hallock said.
At the time of her disappearance, investigators said all statements by the boyfriend "checked out."
