YAKIMA, Wash. — A homeless man accused of raping a drunken 15-year-old girl behind a Toppenish gas station has reached a plea agreeement with prosecutors.

Vincent Matthew Umtuch, 46, pleaded guilty Monday to a charge of third-degree rape of a child in exchange for a sentencing recommendation of 27 months in prison, according to Yakima County Superior Court records.

A second count of third-degree child molestation was dismissed. Sentencing was set for April 8.

The conviction stemmed from an Aug. 30 incident at the Toppenish Texaco on Elm Street.

According to an arrest affidavit, officers were contacting several people drinking beer behind the gas station when an officer looked into an enclosed Dumpster area and saw a man on top of a female on the ground.

The man, identified as Umtuch, had his pants down around his feet, the officer reported, while the female was nude from the waist down. She was also unconscious.

Umtuch was subsequently taken into custody on suspicion of rape. The female turned out to be a 15-year-old girl who apparently had approached Umtuch about buying beer.

Police said Umtuch admitted performing oral sex on the girl but claimed it was consensual. Once revived, the girl said she didn’t remember anything.

According to the plea agreement, the sentencing range per state guidelines is 21 to 27 months. Umtuch said he was pleading guilty only to take advantage of the prosecution’s recommendation of 27 months.
