Homicide investigators with the El Dorado County Cold Case Task Force are trying to solve the nearly 4-year-old murder of Manpreet Singh at the USA gas station on Highway 50 and Lodi Avenue in South Lake Tahoe.

Singh, 27, was gunned down Aug. 6, 2013, while working at the station.

Video surveillance taken at 10:40pm showed a lone gunman walking from Palmira Avenue behind the business.

The District Attorney’s Office has released this video.

Anyone with information is asked to call 530.621.4590.
