Peter Perez was 19 and a resident of San Francisco when he was found dead on April 26, 2006. Authorities treated his death as a homicide after he was discovered with multiple injuries described as consistent with foul play.

The investigation involved multiple law enforcement agencies and many interviews with friends, family members and potential witnesses. Progress was hampered by a lack of concrete evidence and the disappearance of a key witness. Various suspects were identified and questioned but no arrest was made initially and the case remained open and unsolved for a long time.

Does anyone have information about Peter, his last known movements, or witnesses from April 2006?
