Los Angeles ( CNN ) -- Searchers found two hands and two feet Wednesday near the famous `` Hollywood '' sign , the same area where police said a severed head was discovered earlier . A cadaver dog found part of a human hand Wednesday morning about 50 yards from where a severed head was discovered in a Hollywood Hills park on Tuesday , police said . Another hand was located later in the afternoon , and two feet were found Wednesday evening , Los Angeles Police Officer Cleon Joseph said . `` We 're hoping that we can find more remains , '' Los Angeles Police Cmdr . Andrew Smith said . The head , found Tuesday by two people walking dogs along a dirt trail , is that of a man between 40 and 60 years old , with salt-and-pepper-colored hair , Los Angeles County Deputy Chief Coroner Ed Winter said Wednesday . Investigators `` have every reason to believe '' the hands and head belonged to the same person , Smith said . It is possible an animal may have dragged the body parts from where they were initially placed , Smith said . Investigators suspect they had been in the park for about two days . The body parts were found in brush off a secondary trail , about a half-mile from the park entrance , Smith said . At least 30 Los Angeles police officers , a dozen coroner 's investigators , a SWAT team trained in climbing skills and mounted officers were searching a seven-acre section of Bronson Canyon , next to Griffith Park , Smith said . The search effort in the area 's steep terrain was suspended late Wednesday afternoon because of failing light , but searchers will resume work after daylight Thursday , police said . Los Angeles police homicide investigators have begun checking recent missing-person reports for leads on the identity of the man whose head was found , Winter said . The two people who reported finding the head told park rangers they were walking about nine dogs in the Bronson Canyon area of the park around 2:30 p.m. Tuesday when two of the dogs started playing with an object in a plastic grocery bag , police told CNN . The rangers in turn notified robbery and homicide detectives , who are handling the investigation . CNN 's Chuck Conder and Rosalina Nieves and HLN 's Selin Darkalstanian contributed to this report .
