Nhung Nguyen was 46 when she was found dead in a parking lot at the Auburn Mall in February 2014, having suffered a fatal gunshot wound to the head. She was a mother of three. Investigators determined the shooting occurred inside a co-worker’s vehicle during one of their regular carpool trips.

Police focused on co-worker Vu Van Ngo, 30, of Worcester. Early in the inquiry he attempted to shift suspicion to another person, but evidence connected him to the killing. He was charged with murder and later pleaded guilty to manslaughter and to misleading the police. In March 2017 he received a minimum 25-year prison term: 19 years for manslaughter plus a consecutive six- to seven-year term for obstructing the investigation.

If anyone knew Nhung Nguyen, her routines, or the carpool she rode in, please share what you remember with authorities.
