Sarah Roberts was 26 when she was shot and killed in Fresno, California, just after midnight on January 1, 2012. She had been at a New Year’s Eve party and is described as a young mother of two who was apparently an unintended victim caught in crossfire of a nearby altercation.

No arrests have been announced. Investigators say the inquiry has been hampered by a lack of witnesses willing to come forward, and Valley Crime Stoppers has offered a reward for information that could help solve the case.

If anyone was in the area that night or remembers details about the altercation, please share what you know with investigators or Valley Crime Stoppers.
