The El Paso County Sheriff's Department says one of the Fort Carson soldiers under investigation by the Army on allegations of sexual misconduct is the subject of a separate investigation by sheriff's deputies.
Sheriff's Lt. Jeff Kramer says his department learned Friday of the parallel investigations.
Fort Carson confirmed Wednesday the Army is investigating several soldiers on allegations of sexual misconduct involving under-age girls.
Fort Carson didn't say how many soldiers were under investigation, where the alleged misconduct took place or how many girls were allegedly involved.
Kramer says the alleged incident under investigation by the sheriff's department involved a 14-year-old girl and happened off-post. He says the sheriff's investigation is continuing.
Fort Carson is an infantry post outside Colorado Springs. Some of the post is in El Paso County.
