BOULDER COUNTY, Colo. -- A man walking down Highway 287 shot at a deputy on Saturday night, the Boulder County Sheriff's Office said.
The sheriff's office said it happened about 5:15 p.m. near Highway 287 and Oxford Road, south of Longmont. The deputy, identified Monday as 19-year veteran Teri Javes, was not injured.
The man, identified Monday as 37-year-old Adrian Joseph Shaffer, was walking down Highway 287 with no shirt and a gun, acting aggressively toward drivers, the sheriff's office said.
When Javes responded, the suspect immediately started firing at her SUV. The deputy returned fire and the suspect was hit multiple times, the sheriff's office said.
The suspect was transported to an area hospital with gunshot wounds. He was reported in grave condition Monday at a Denver-area hospital. There was only one deputy involved in the incident.
Shaffer has an extensive criminal history, and he's under investigation for attempted first-degree murder of a peace officer and other crimes.
Highway 287 was closed in the area from Niwot Road to Oxford Road while the sheriff's office investigated.
