UPDATE: "Security hold" placed on case of Pico Rivera body discovery

PICO RIVERA -- Los Angeles County sheriff's investigators have blocked coroner's officials from releasing information regarding the discovery of a body buried in a Pico Rivera backyard earlier this week.
The identity, and any other information regarding the male body found about 6:30 p.m. Wednesday in the 8500 block of Pico Vista Road, was not available Friday due to a "security hold" placed on the case by the sheriff's department, Los Angeles County Department of Coroner's Assistant Chief of Operations Ed Winter said.
According to sheriff's Capt. Michael Parker, a loved one and acquaintances went to the home looking for a person who had been missing for several days.
They found a human remains buried in a shallow grave and called authorities, he said.
People at the scene Thursday who identified themselves as family members of the 19-year-old missing man said they strongly believed the body was his, though sheriff's and coroner's officials had not officially identified the remains.
It was unclear Friday whether the security hold prevented family members of the person found buried in the backyard from receiving official notification of his death.
Under a security hold, "We can't give any information to anybody," Winter said, including family members of the decedent.
Sheriff's investigators, however, may notify the family members if they choose, Winter added.
The handling detective could not be reached for comment Friday.
