Los Angeles police were called to Bronson Canyon Park Tuesday afternoon after dog walkers found a human head inside a bag, authorities reported. Two dog walkers discovered the severed head of an alleged homicide victim at about 2:30 p.m. near the 3200 block of Canyon Drive,  according to an advisory from the Los Angeles Police Department . The hikers had about nine dogs on the trail when two of the dogs started playing with an object in a bag. When the hikers realized it was a human head, they immediately notified park rangers. Investigators were at the scene Tuesday evening seeking clues and possibly more body parts, but suspended their search when it grew dark. The crime scene will be guarded by LAPD officers. The head appeared to belong to a male and was likely not in the area for long. The Los Angeles County coroner’s office will analyze the remains. Bronson Canyon Park is a popular recreational area inside Griffith Park. Trails in the park lead to a view of the Hollywood sign and also an area known as the “Batcave,” which was used in the 1960s television show  Batman .
