Police announced the arrest of Gabriel Campos Martinez, 38, for the 2012 murder of Hervey Coronado Medellin, 66, of Los Angeles. Campos Martinez was arrested in San Antonio, Texas, on Sunday with the help of local authorities and is being held without bail while he awaits extradition proceedings.
Two women discovered Medellin's head while walking dogs on a trail in Griffith Park. One of the dogs, which was off its leash, had started to play with a plastic bag. When the dog shook the bag, the head fell out.
More than 120 police officers, firefighters and Los Angeles County sheriff's deputies searched 7 acres of the park during a two-day search.
Another cadaver dog helped find more body parts, including hands and feet, near the same area where the head was discovered.
Police have said they believe the victim was killed elsewhere and his remains dumped just inside the park, which attracts hundreds of hikers and dog walkers on most days.
Although rustic, it is just a short distance from film studios and other Hollywood attractions.
