COLORADO SPRINGS, COLO. -- The trial for the former wrestling coach accused of sexually assaulting at least 22 boys continued Tuesday as experts testified Joshua Carrier was not medically licensed to perform "skin checks," contrary to what the boys he claimed.

The alleged victims had testified through the trial that they trusted Carrier, a former Colorado Springs Police officer, because he had told them he was an emergency medical technician (EMT).

However, an EMT enforcement coordinator for Colorado who conducts investigations for EMT applicants said there is no record of Carrier in the EMT registry.

Carrier is accused of more than 200 criminal charges after allegedly touching the boys inappropriately during what he called routine "skin checks." The checks are exams performed by doctors and coaches on wrestlers to check for ringworm, lesions and other injuries that may keep a wrestler from competing.

The boys who testified over the past three weeks all said they had to weigh-in wearing only "whitey tighties" or nothing at all. They also said Carrier would have them pulled from class for second checks if he saw something during the initial round. The second time is when many of them claimed he would touch their genital area.

Most boys said they trusted Carrier not only because he was a police officer but because he told the boys he was an EMT, which prosecutors claim was just an excuse to get close to them.

The enforcement coordinator said a person cannot claim to be an EMT without certification, but a person can be a trainer at a school.

Carrier received certificates for completing EMT classes at Pikes Peak Community College, according to a coordinator with the program, but that doesn't make him a licensed EMT.

Carrier assisted with the Horace Mann Middle School team last year after serving as the school's Resource Officer the year before.

Prosecutors are expected to rest their case Wednesday as the trial continues. If Carrier is found guilty, he could face life in prison.
