Additional charges have now been filed against a Larimer County Middle School teacher, according to the Larimer County Sheriff's Office.

According to a post on the Sheriff's Office Facebook Page, Robert Denise was already charged with three counts of Sexual Assault On A Child by One In a Position of Trust, which is a third-degree felony under Colorado law. But the sheriff's office says now another alleged victim has come forward. The latest accuser attended Cache La Poudre Junior High School [now middle school]  in the early 2000s. He told investigators that Denise engaged in grooming behavior leading up to a sexual assault. He also told Denise that he had been sexually abused years earlier. Denise as a teacher was required to report that information but investigators say there is no indication that he ever did so.

According to the post:

''Denise now faces a total of four counts of Sexual Assault on a Child by One in a Position of Trust (F3) against three victims, all of whom were under the age of 16 when the incidents were reported to have occurred. The victims do not know each other and did not attend CLP at the same time. Denise has also been charged with Failure to Report Child Abuse (M3).''

Besides working as a teacher by the Poudre School District since 1995, Denise also worked at the Ben Delatour Scout Ranch in Red Feather Lakes during summers in the 1990s. Because of the allegations and Denise's frequent access to children over many years, investigators are concerned that other vicitms may exist.

Because of that, anyone who may know about about unreported inappropriate conduct or abuse involving Robert Denise is being asked to contact Investigator Ryan Gebhardt at 970-498-5586. Those who want to remain anonymous may also contact Crime Stoppers of Larimer County at 970-221-6868 or www.stopcriminals.org.
