A Natrona County man accused of sexually assaulting a woman at gun point has his preliminary court hearing.

Previously unreleased information has surfaced in a case against a Natrona County man who is accused of raping a nineteen-year-old woman at gunpoint in his Casper Mountain Cabin. According to an investigator's testimony given Thursday morning in a preliminary hearing, on the night of February seventeenth, brandishing a Colt forty-five caliber handgun, twenty-nine-year-old Jensen Frandsen Winkler allegedly held the victim captive in handcuffs for twelve hours in his cabin on Crimson Dawn Road.

Suspected to be under the influence of drugs and alcohol, Winkler told the victim that he would let her go if she gave him the best oral sex of his life. Investigators say that Winkler apparently wasn't satisfied and then removed her clothing and raped her.

At one point, Winkler allegedly "hogtied" the victim using electrical tape and stuffed her underwear in her mouth using the same roll of tape to gag her.

When Natrona County deputies arrived on scene in response to a 911 call, they reported that the victim was waiting in a car and Winkler was dressed in camouflaged pants and a military style tactical vest with grenades attached. Winkler also reportedly told authorities that he had an AK-47 with armor piercing rounds. It was later determined that as real as the grenades looked they were indeed fake.

Winkler is being kept in the Natrona County Detention Center on a seven-hundred and fifty thousand dollar bond and faces two sexual assault charges, kidnapping, aggravated assault and two drug charges.

A guilty conviction could land Winkler in prison for life.
