Cold Case Spotlight

On August 7, 2006, at approximately 10:23 pm, 17-year-old Robert Placencia was struck by gunfire, while walking in the area of Tamoshanter Way and Montecito Way in the Meadowview area of Sacramento, California. Two other murders happened in the same area within 30 hours of Robert Placencia's killing but are not considered connected and appear to have been gang-related. Robert's son was 12 months old when his father was shot and killed in what appears to be a case of mistaken identity. In 2007 a $50,000 Governors Reward was issued and still remains active for information leading to the arrest and conviction of the suspect(s). Please contact Detective Kirtlan at the Sacramento Police Department Homicide Unit at (916) 808-0678 if you have any information. Callers that wish to remain anonymous may be eligible for a reward of up to $1,000 through Crime Alert at (916) 443-HELP (4357) or text in a tip to 274637 (CRIMES).
