On the morning of May 22, 2016, Auburn Police Officer Ronald Tarentino Jr., 42, was shot and killed after stopping a vehicle on Rochdale Street. As he approached the car an occupant opened fire, striking him multiple times; he was taken to UMass Memorial Medical Center and later died. Tarentino had served two years with Auburn after seven years with Leicester Police, and was a husband and father of three.

Authorities identified 35-year-old Jorge Zambrano as the shooter. Zambrano fled, triggering a nearly 18-hour manhunt that ended at a duplex in Oxford when he emerged from a closet and opened fire on officers. A Massachusetts State Police trooper was hit in the shoulder during the exchange; officers returned fire and Zambrano was killed at the scene.

Reports state Zambrano had a lengthy violent record and had been released from prison in 2013. Days before the traffic stop he had been arrested for driving with a suspended license and improper plates and was released on personal recognizance; a review of those court decisions was opened after the killing. If anyone knew Officer Tarentino or has information about the case, please share what can help.
