Andrea Lafon, 20, was fatally shot while sitting in a car with a friend in North Las Vegas on the evening of September 5, 2014. The shooting happened about 7:15 p.m. near Ann Road and Losee Road, in the 2600 block of Small Mountain Avenue; Lafon was struck in the head, taken to University Medical Center in extremely critical condition, and pronounced dead the next morning.

Police initially reported the encounter as a drug deal that turned violent: Lafon and her companion were meeting people on foot to sell marijuana when an argument escalated and one person fired into the vehicle. A 16-year-old student, Patrick Wayne Harper, was arrested on September 11, 2014, to be charged as an adult after a witness identified him and a report said the dispute began when Lafon refused to sell $40 worth of marijuana for $35. That case was dropped weeks later when defense counsel produced surveillance video placing Harper at a convenience store miles away minutes before the shooting.

No other arrests have been announced and the investigation has gone cold. Vigils have been held by family and friends. Does anyone have information that could help bring Andrea’s killer to justice?
