It all sounds eerily similar to a 2012 discovery not too far away. KCAL reports a hiker found a man's severed head in a plastic bag in the same area. Authorities later discovered his hands and feet near the trail.
That victim's boyfriend was convicted of murder and sentenced to 25 years to life in prison last fall.
As for the new remains, a coroner told KABC it'll take more than a week to determine the victim's age and gender.
