Larry Dale Floyd, a 62-year-old constable from The Colony, was arrested on suspicion of soliciting to have sex with a child and was charged with seven related crimes, Cañon City police said.

Mr. Floyd was being held at the Fremont County Detention Center in southern Colorado on $100,000 cash-only bail. He could not be reached for comment.

Texas and Colorado investigators are looking into Mr. Floyd's life for evidence of other encounters with children, said Dave Bodycomb, a Cañon City police records clerk.

Investigators would not comment further, but court papers detail sexually explicit conversations with an undercover officer dating to June 2.

Charges against Mr. Floyd include conspiracy and criminal intent to commit sexual assault on a child, pandering of a child, inducement of child prostitution, trafficking in children, criminal solicitation, solicitation for child prostitution and enticement of a child.

A person using the screen name freevacation_formoms contacted Marsha – the undercover officer's alias – through an online instant messaging service, according to the statement of probable cause released by the clerk's office of the Fremont County Combined Court.

The person identified himself as Rick from Oklahoma. He described himself as a "very real older male, clean, safe, discreet" with "a motor home so will travel," according to the document.

Rick asked about Marsha's 8-year-old daughter, Melissa. He "told me that he had no limits, none at all, other than moms rule," the officer wrote in the court document.
