A woman who worked for the Jefferson County Sheriff’s Office for about three years has been arrested for suspicion of a number of crimes.

Following an investigation by the sheriff’s office, an arrest warrant for Myriah Lynn Lovato, 29, was issued on Jan. 18 and she surrendered herself that evening, according to Sheriff Jeff Shrader.

“It’s our intent to always serve you with integrity, excellence and respect,” said Shrader in a video press statement released last week. “Unfortunately, it appears that one of our own has failed in this regard.”

Lovato was arrested and charged with unlawful possession of a controlled substance, introducing contraband in the first and second degree and sexual conduct in a correctional institution. All are felony charges. She is also facing misdemeanors —first degree official misconduct and possession of drug paraphernalia.

According to a press release, the Jefferson County Sheriff’s Office hired Lovato on Jan. 7, 2016, and she was assigned to the Detentions Services Division on June 12 that year, after she completed the Colorado Peace Officer Standards and Training (POST) academy.

The Jeffco sheriff’s office’s investigation began on Dec. 22 after deputies were informed of employee misconduct, states a press release. That day, Lovato was placed on unpaid administrative leave pending the outcome of the investigation, the press release states. She submitted a letter of resignation on Jan. 2.

“It is extremely disheartening and frustrating when one of our own becomes the subject of an investigation, is facing felony charges and potential jail time,” Shrader said in his press statement. “More disheartening is that this has subjected other deputies, as well as the inmate population, to additional and unnecessary risk.”

In his statements, Shrader added that Lovato, as are all charged suspects, presumed innocent until proven guilty.
