COLORADO SPRINGS, Colo. -- A former basketball coach at a Monument charter school in Colorado is being accused of dozens of counts of child abuse, sexual assault and other crimes.

The Colorado Springs Gazette reported that Gregory Lynn Burr, 28, is accused of regularly hitting players in the groin, exposing them to pornography, and pouring water on them when the weather was cold.

Burr faces 39 charges including child abuse resulting in serious injury in the case, which involves 10 teenagers 14 to 17 years old. The incidents allegedly took place from September 2005 to March 2006 at the Monument Academy. Court records show he posted bail last month.

In court documents examined by the Gazette, former basketball players said Burr routinely struck players in the groin with his hand, basketballs and tennis balls and laughed about it. One player claimed permanent injury.

The paper reported that one boy had scrotal surgery for an injury he attributed to the coach's strikes. Police said other students said the strikes to the testicles were "the kind of hits that made you lay down" or "made you stop for a minute to catch your breath," according to the Gazette.

Others said Burr showed them pornography on his home computer. They said that the pornography included images of men with disfigured penises and women with several body piercings.

Burr's attorney, Phil Dubois, said the charges are unwarranted.

"Mr. Burr is not a sex offender or anything close to it," Dubois said.

Arrest records showed that the boys believed the incidents were the coach's attempts at humor and that they kept quiet about them because they feared they'd be booted from the team.

One student said Burr would ask the boys what the capital of Thailand was and when they would answer, "Bangkok," he would hit their groin area.

Some students said that Burr poured water on them and rolled down windows of the car during cold weather, when they were going to or from games. The paper reported that one student claimed Burr made him get out of the car and run behind it. Another said he was told to run around a rest area in the nude.

Burr is no longer employed by the Monument Academy.

Monument is located 45 miles south of Denver, between Denver and Colorado Springs.
