The new year of violence began with the shooting outside Club Set in the 2900 block of Travis Street when those uniformed Harris County deputies were working extra jobs. Investigators said 25-year-old Joseph Anthony Gonzalez confronted the deputies with a gun during a fight in the parking lot and shot all three of them. One of the deputies returned fire and hit Gonzalez, the sheriff's office said. During the confrontation, Gonzalez's mother was shot in the leg and later died at the hospital. The investigation into whose gunfire hit her was still ongoing at last check.

Houston fire investigator fatally shot during arson surveillance
A rash of intentionally set fires in a Heights-area neighborhood prompted Houston Fire Department arson investigators to converge on the area in October, including Lemuel "DJ" Bruce. Bruce was shot and killed while tailing a suspect. According to ABC13 sources, Bruce and five other investigators were in the Timbergrove area, but they weren't looking for a suspect in particular and none of them was expecting to make a traffic stop in the neighborhood. The suspect was found nearby dead of a self-inflicted gunshot wound.
Earlier in the year, a Harris County deputy was fired upon while working an off-duty security job in October at a west Houston apartment complex, and officers were shot at in a Montrose-area neighborhood in a separate incident. The armed suspect was shot to death in that incident.
