MISSOULA, Mont. (AP) — A Missoula County sheriff's deputy has been fired due to information uncovered during an investigation of a complaint that he was having an inappropriate relationship with a 17-year-old girl.

Sheriff Carl Ibsen on Thursday announced the firing of Deputy Larry Schwindt, who had been with the department for just over two years.

Ibsen says Schwindt's alleged relationship with the girl, which reportedly began about a year ago, is being investigated by the Professional Standards Division. Detectives also are investigating to determine if criminal charges are warranted.

Ibsen says information already uncovered led to Schwindt's firing. The sheriff declined to say what was discovered or describe the nature of the relationship.

There is no phone listing for Schwindt in the Missoula area.
