ENCAMPMENT - Law enforcement officers from Rock Springs and Walden, Colo., were injured in separate incidents recently, resulting in charges against two students in Laramie, and a retired Rock Springs doctor.

In the first incident, Rock Springs Police officer Brenda Baker was struck with the mirror of a passing vehicle as she made a traffic stop in the 1400 block of Elk Street in Rock Springs at 11 p.m. Friday. Shortly after Baker was hit, a Rock Spring Police officer arrested Dr. Richard Walker, 74, of Rock Springs, subsequently charging him with driving while under the influence of alcohol.

At the time of his arrest, Dr. Walker was driving a dark colored Ford Taurus in the 1600 block of Elk Street, according to a release.

An independent investigation by Wyoming Highway Patrol into the incident where Officer Baker was struck with a vehicle indicates that the vehicle Dr. Walker was driving matched the description of the vehicle that hit Baker.

Investigators also had physical evidence from the scene of the accident to support additional charges against Walker for leaving the scene of an accident.

Other charges also could be filed, according to Commander Matt Kesler of the Rock Springs Police Department.

Officer Baker was treated and released from the Sweetwater County Medical Center. She remains on leave from the department pending release by Workers' Compensation to return to active duty, Kesler said.

In a separate incident, Jackson County Sheriff Rick Rizor of Walden, Colo., was injured early Monday morning as he and another deputy from his department attempted to set up a rolling road block in order to stop two Laramie men who fled the Wyoming Technical Institute about 1 a.m., Jackson County Undersheriff Rich Castle said.

Joshua Rondeau, 22, and Justin Ayers, 20, both of Vermont, led Albany County Sheriff's Department officers on a high speed chase through Laramie after officers responded to a report of two individuals attempting to break into a pop machine at the Wyoming Technical Institute. When officers approached the two, who are students at Wyo Tech, the young men fled, according to a release from the Albany County Sheriff's Department.

The vehicle, driven by Rondeau, allegedly attempted to hit one of the Albany County Sheriff's vehicles before it went through Laramie on 3rd Street, then went across the Clark Street viaduct and onto Wyoming Highway 230, the release said.

The chase, at speeds in excess of 90 miles per hour, ended in Colorado on Highway 125 two miles north of Cowdrey and about 12 miles south of the Wyoming-Colorado line.

When the Albany County officers realized the fleeing suspects were headed into Colorado, they contacted the Jackson County Sheriff's Office for assistance. Sheriff Rizor and a deputy, in separate vehicles, attempted to establish a rolling road block, but at the high rate of speed the suspects were driving they hit the vehicle driven by Rizor, causing it to leave the road and roll several times into the ditch.

The suspects' vehicle also left the road and was disabled. Rizor, Rondeau and Ayers were all injured in the incident and were transported to Ivinson Memorial Hospital in Laramie where they were treated and released. The sheriff had returned to work by Tuesday, Undersheriff Rich Castle said.

The suspects are currently incarcerated in Laramie at the Albany County Detention Center, Castle said.

Rondeau and Ayers are charged in Albany County with eluding a law enforcement officer, aggravated assault, and burglary to a coin machine.

Felony charges are pending in Colorado, Castle said. The Colorado investigation is being handled by the Colorado State Patrol.
