GRAND JUNCTION, Colo. -

A Former District Attorney for the 7th Judicial District of Colorado pleads guilty in an unlawful sexual contact case.

Colorado Attorney General John Suthers announced today that Myrl Serra pleaded guilty in Montrose District Court to criminal extortion, a class-four felony, and unlawful sexual contact, a class-one misdemeanor.

The unlawful sexual contact charge involved three victims. In pleading guilty, Serra acknowledges that sufficient evidence exists for a jury to find him guilty beyond a reasonable doubt.

As part of the plea agreement, Serra could face up to 12 years in prison and will be required to register as a convicted sex offender. Sentencing will be Jan. 19.

Police arrested Myrl Serra in September 2010 on suspicion of unlawful sexual contact with force, criminal extortion, indecent exposure and official misconduct.

A Montrose jury previously convicted Serra of three counts of violating the conditions of his bond, a felony, in August. Serra also faces a mandatory prison sentence following his conviction at trial for a felony bond violation involving one of his three victims. The sentence imposed will run consecutive to any sentence the judge levies on the criminal extortion and unlawful sexual contact charges.

Allegations against Serra include cornering a female worker inside his office in April 2010, grabbing her breast and forcing her to touch his genitals.

A jury last month convicted Serra of harassment and violating his bail conditions. He voluntarily turned himself to jail shortly after his conviction.
