Ronald Howard Durland had been drinking when the two 16-year-old boys showed up unexpectedly at his Oregon City home.

The boys came to see Durland's teenage daughter on April 17. Durland told the boys that he was suspicious of their intentions. No funny business, he told them.

To drive home his point, Durland held the blade of his folding knife against the throat of each boy and threatened to cut off their genitals, said Clackamas County prosecutor Mike Regan.

The boys said they had stopped by for a social visit and nothing more, Regan said.

Durland admitted to police that he had been drinking vodka before the confrontation but denied having a knife, Regan said.

Durland, 55, pleaded guilty Tuesday to two counts of unlawful use of a weapon and was sentenced to 90 days in jail. Durland is on probation for possession of meth and driving under the influence of intoxicants.

"He wanted to impress on those kids not to monkey around with his daughter," said Leonard Kovac, Durland's attorney. "He stepped over the line but in no way did he intend to follow through."

Durland did not address the court and his victims did not attend the sentencing.
