An undercover Houston police officer was killed Tuesday night in a shootout at a Walgreens parking lot. Officer Henry Canales, 42, was shot during a reverse sting operation that was being conducted by HPD's Burglary, Theft and Auto Division around 9:40 p.m. outside the pharmacy at Bellaire and Hillcroft in southwest Houston. Canales was a 16-year veteran with the police force and had spent 12 years in the Tactical Division. During his time with the Tactical Division, Canales was part of a group called "Beat the Heat."
