A man apparently walked in to the Alhambra police station Friday claiming he knew where the skeletal remains were buried.
Officers followed the tip and found the remains in the backyard of the home located in the 9400 block of Cortada Street. The residents of the home apparently had no relation with the victim.
A sheriff's spokesperson said the remains appear to be several years old. A preliminary examination led detectives to believe that the remains are of an Asian woman between the ages of 40 and 60.
"This is really weird because we've been living here for a long time and we've never seen anything like that," neighbor Ivan Villa said. "I saw a table out there and they found some dirty pants."
The tipster, identified as 27-year-old Johnny Huynh of Rosemead, was booked on suspicion of murder and was being held on $1 million bail.
"It's unusual," said Sgt. Ken Perry of the Los Angeles County Sheriff's Department. "It's what we hope for, the person that can't live with it anymore that comes in and gives up information whether they did it or knows somebody else who did it to points us in the right direction to either find a missing loved one, a murdered person or points us at a suspect."
