The body of a missing California woman was reportedly identified Tuesday after being discovered in a remote part of the Cleveland National Forest.

Orange County Sheriff’s Department officials said the remains of 27-year-old Erica Alonso were discovered late Monday night by Caltrans biologists.

The coroner is scheduled to do an autopsy Wednesday to determine the cause of death, but Isaac Alonso, the father of Erica, believes someone had killed her.

“Whoever did it, I want them to pay,” he told the Orange County Register. “I want justice.”

Alonso disappeared on Feb. 15. Authorities say, Alonso went out with a boyfriend for Valentine’s Day and they befriended another couple at a lounge in Costa Mesa.

They left with the couple at 1:30 a.m. and went to the boyfriend’s home in Irvine. At around 3:45 a.m., Alonso left the home following an argument, a sheriff’s spokesman said.

Alonso’s family called the police two days later after she failed to show up to work.

Over the next month, friends and family began an online crowdfund account to raise money for the search. The Alonso family also offered a $5,000 reward for information that would help find the woman.

Sheriff’s deputies found her car on March 25 in Aliso Viejo.

Monday night, a group of biologists were walking through the forest around 10:30 p.m. and found a body about a mile outside the U.S. Forest Service San Juan Fire Station near the Ortega Highway.

The preliminary identification is pending fingerprints and dental records from the scheduled autopsy.

Isaac Alonso said Tuesday night that he is confident the person responsible for his daughter’s death will be caught.
