A Columbia Falls man pleaded guilty on Tuesday in Flathead District Court to his second sex offense committed against a child.

Jacob Dean Dalager, 22, pleaded guilty to one felony count of sexual abuse of children as part of a plea agreement in which another sex charge was dropped.

Dalager acknowledged on the witness stand that he accepted nude pictures via Facebook from a girl under 16 years old in 2013.

“There was some dispute over her age and what you knew,” defense attorney Vicki Frazier said of her client’s knowledge about the girl’s age during Dalager’s confessions on the witness stand.

Prosecutor Andrew Clegg got Dalager to admit that there was a good chance the state could prove that Dalager knew the girl was underage based on Facebook messages he sent to an acquaintance.

Dalager is a registered sex offender. He was convicted of sexual intercourse without consent in 2012 for giving a 6-year-old girl $6 to perform a sex act.

Flathead District Judge Amy Eddy accepted Dalager’s plea and said that she and Flathead District Judge Heidi Ulbricht would discuss who would sentence Dalager. Ulbricht is presiding over the 2011 case for which Dalager will face a hearing for possible revocation of probation. The new felony conviction is a violation of Dalager’s probation.

Dalager is set to be sentenced in June.
