Clinton Greenwood, 57, was ambushed and shot outside the Baytown courthouse in Texas on April 3, 2017, as he arrived for work. Greenwood, who served as Assistant Chief Deputy with the Harris County Precinct 3 Constable’s Office and had previously been a Major leading the Harris County Sheriff’s Office Internal Affairs Division, radioed for help but later died at Memorial Hermann Hospital. He was a graduate of Rice University and South Texas College of Law.

Investigators tied the killing to 64-year-old William Francis Kenney, who had a long-standing grudge against the Harris County Sheriff’s Office and a history of filing complaints against county officials. Surveillance footage placed Kenney near the courthouse that day, a rental car used in the crime was traced to him, and Kenney died by suicide the day after the murder using the same firearm.

Greenwood was remembered by colleagues for his dedication and service. If anyone knew Greenwood, Kenney, or observed activity near the Baytown courthouse on April 3, 2017, please share what you know.
