There's enough evidence against a 16-year-old Lakeville girl to try her on 10 counts, including kidnapping and aggravated robbery, in the brutal group beating of a mentally disabled man, a Dakota County judge ruled Tuesday.

Judge Michael J. Mayer said Natasha Dahn will be held without bail until a hearing Nov. 20, which will determine whether she'll be certified to stand trial as an adult for her alleged role in the beating of Justin Hamilton Oct. 10 and 11 in southern Dakota County.

Hamilton, 24, of Lakeville, is recovering from the attacks, which Dahn allegedly set off by lying to her boyfriend, claiming that Hamilton had hit her. That man, John Maniglia, and three others went after Hamilton, beating and threatening him for hours on a Friday and Saturday night, with Dahn egging them on and kicking him, court papers say.

Hamilton, who has fetal alcohol syndrome, recently befriended Dahn. In an interview, Dave Bellows, chief deputy of the Dakota County sheriff's office, said the "gratuitous violence" included luring the man to a remote area where he was beaten and tortured.

Tuesday, Dahn shuffled into a juvenile courtroom in Hastings, ankles shackled and wrists cuffed. She peered out glumly from behind small, dark-framed eyeglasses, her long brown hair in a ponytail, dyed black bangs over one eye, as Mayer said some of the charges could lead to prison.

Allegedly leading the assaults on both nights were Maniglia, 19, and Jonathan Diepold, 21, of Northfield, who face 10 felony counts, including kidnapping, assault and robbery.

Glen Ries, 33, also of Northfield, faces five counts on similar charges and has been fired from working with vulnerable adults in Northfield.

Timothy Ketterling, 21, of Prior Lake, is charged with false imprisonment, theft and third-degree assault. Ketterling, who also is mentally disabled, posted bail.

The other three men remain in the Dakota County jail.
