Human remains were discovered Tuesday in a residential area of Montebello.
Detectives were called to a location in the 900 block of North Lincoln Avenue (map) just after 4 p.m. when pipeline maintenance workers discovered unusual debris resembling human remains.
North Lincoln Avenue, between San Gabriel Boulevard and La Merced, will be closed until further notice, authorities said.
The area is not far from the Rio Hondo Bike Trail where human remains were discovered in July by a cyclist.
Authorities don’t know if the two incidents are related, but Deputy Mark Pope told KTLA that any possible connection was being investigated.
Anyone with information was urged to call the Los Angeles County Sheriff’s Department’s Homicide Bureau at (323) 890-5500.
