AUSTIN (KXAN) -- The windows at Austin Police Headquarters are finally being replaced nearly a year after a man went on a shooting rampage in downtown Austin.

Police say the work started this week and won't be finished until Friday, Nov. 20. While crews work on replacing the upper windows, the lobby and front plaza will be closed to the public Monday, Nov. 9 - Friday, Nov. 13.

KBR, a Houston-based construction contractor specializing in defense and government building and repair contracts is doing the work. The total cost for the replacement windows will be $130,819.

On Nov. 28, 2014, Larry McQuilliams, 49, fired hundreds of rounds at the Mexican Consulate, Federal Courthouse and the Austin Police Department headquarters. APD Sgt. Adam Johnson was in the process of putting up a couple of Mounted Patrol horses when he heard the gunshots outside of the APD building. Police say while holding the reins of two horses, Johnson fired one round, from 312 feet away, at the shooter, killing McQuilliams. No one else was injured during McQuilliams' 10-minute shootout.
