Sylvia Chavarria, a 28-year-old resident of Modesto, California, was found dead in the backyard of a South Modesto residence on June 1, 2016, after reports of gunshots around midnight. Emergency medical personnel pronounced her dead at the scene. The Stanislaus County Sheriff’s Department treated the death as a homicide and investigated, but no suspect information was released and officials did not disclose details such as how many times she was shot.

Residents described the neighborhood as troubled with frequent police activity, a factor investigators said complicated efforts to reconstruct events and identify witnesses. Chavarria had previously been the victim of a 2007 attack by then-boyfriend Jesus Contreras Galvan, who was later convicted of attempted murder, kidnapping, felony domestic violence and criminal threats and sentenced to eight years to life; no direct connection between that conviction and the 2016 killing has been established.

Did anyone in Modesto hear about or see activity in that South Modesto block around midnight on June 1, 2016?
