WESTMINSTER, Colo. A trooper with Colorado State Patrol (CSP), who was completing reports in a protected median of a highway in Westminster, "looked at the face of evil" Saturday when a driver opened fire at him, striking his arm, a CSP colonel said. But "we came out on top today," he added. CSP Col. Matthew Packard identified the injured trooper as Ty Simcox, a 16-year veteran of CSP. He has been released from the hospital. The incident started around 1:18 p.m., when Trooper Simcox was in his marked patrol vehicle in the center median of Highway 36 eastbound, west of Federal Boulevard. He was parked in between two concrete barriers working on reporting paperwork, Packard said. A driver in a black Chevrolet pickup truck slowed as he went by the trooper, and shot several rounds from a semi automatic handgun at the patrol car, Packard said, and one round hit Trooper Simcox in his arm. The suspect driver then pulled over on the left shoulder, left his car and began to fire at the windshield of the CSP patrol vehicle, hitting the car several times, Packard said. "Our trooper exited his patrol car and immediately began to return fire," Packard said. "He deployed his rifle that was issued to him, and was able to strike, and ultimately killed the suspect that was attacking him."Trooper Simcox applied a tourniquet to his arm until another trooper one Simcox had trained at CSP arrived at the scene. He was then transported to Denver Health Medical Center with injuries that were not life-threatening. He has since been released to go home. Packard said authorities do not yet know why the suspect targeted the trooper. The suspect has not yet been identified. Watch the full press conference in the video below. Update on shooting on US 36 in Westminster where CSP trooper was shot by suspect"I will tell you very directly that our member was targeted today by a man that intended to kill him, and that is shocking and unacceptable, but our Colorado State trooper responded appropriately and swiftly and courageously, and he won today," Packard said. "And by winning, not only did he save his own life, but he saved the rest of this community from someone that was clearly intending to do evil. And I want it to be known that we came out on top today. And that's really, really important, because that's what good does. Good and courageous people win over evil cowardice, and that's what happened today on Highway 36."He said Trooper Simcox acted heroically."He looked at the face of evil and responded appropriately and won," Packard said. All lanes of US 36 in Westminster along a 2.5-mile stretch between Lowell Boulevard and Federal Boulevard remain closed for the investigation as of 5 p.m. Saturday. Crime scene investigators responded to the scene on US 36 4:30 p.m. and will need to scour the area before the road can reopen. It will likely be a couple hours, Packard said. "It was seconds, but it felt like minutes," Rebecca Quintana, a witness, told Denver7. "It was like slow motion, but then it felt like it happened so fast."This is a developing story.
