Witnesses say they saw an Adams County Sheriff’s Deputy kick a suspect off the roof during a foot chase, a news release from Weld County District Attorney said.

James Cook, a 33-year-old K9 handler, is charged with second-degree assault that caused serious bodily injury, which is a class four felony.

According to the affidavit, several officers from multiple agencies responded March 21 at about 3 p.m. to the 12000 block of WCR 4. They were looking for domestic violence suspect Alejandro Martinez.

Martinez ran away from them and was found later on the roof of an outbuilding on the property, said officers from Brighton Police and the sheriff’s office.

Cook climbed onto the roof with his K9, Bayou, to arrest Martinez after he refused to come down. Cook told Martinez twice to get down or he would tell the dog to bite him, according to his police report.

Martinez did nothing, and Cook walked toward him with Bayou. Cook said in his report he then lost his footing and slid into Martinez.

But a Brighton Police officer and a nearby homeowner said Cook deliberately kicked Martinez off the roof.

Martinez was taken into custody and transported to Good Samaritan in Lafayette, where it was found he had a broken pelvis.

Cook was formerly charged with second-degree assault on April 13 after an investigation by the Weld County Sheriff’s Office. Cook appeared in court for his bond hearing the next day.

Bond was set at $5,000, and Cook’s next court appearance is still to be determined.
