(Watertown) The Wisconsin Department of Justice has identified the person shot and killed by a Watertown Police Officer last month. Officers had been looking for Thomas Jeffery to question the 32-year-old about his involvement in a domestic incident. Officers initiated a traffic stop of the suspect’s vehicle for a burnt-out taillight on May 31. During the stop, a taser was deployed, but was not effective. Shots were fired from within the vehicle and officers returned fire. Officers began life-saving measures and paramedics later transported him to a nearby hospital where died. A firearm was found in the vehicle. No other injuries were reported. The officer involved has been identified as Pedro Gallegos, who has been in law enforcement for six years. Gallegos was placed on administrative leave, per department policy. The Justice Department is continuing to review evidence and will turn over their reports to the Jefferson County District Attorney once the investigation concludes.
