Norberto Martinez was 36 and a resident of Turlock, California when he died of a stabbing on July 25, 2017. The Stanislaus County Sheriff’s Department treated the death as a violent crime and opened a comprehensive investigation.

Investigators identified several people of interest and suspects. Miguel Ivan Tamayo Martinez was named a key suspect and surrendered to authorities. Both Norberto Martinez and Severiano Martinez were also listed as persons of interest in a related stabbing incident in Salida, suggesting a possible link between the two events. Norberto’s past included a 2010 arrest for probation revocation, a detail noted during the inquiry.

The case involved multiple individuals and investigators worked to untangle the connections and motives.
