LEWISTON — A Wilton woman who stole a young girl’s flip-flops then made her watch as she used the toilet was found not criminally responsible and committed to a psychiatric hospital, according to court records.

Chrystal Rose, 36, had been indicted by an Androscoggin County grand jury on nine charges, including two felonies.

The charges stem from an incident last summer when she entered the Livermore Falls home of a 13-year-old girl by posing as a public servant, according to a police affidavit. Rose told the girl the blue flip-flops she wore belonged to Rose, then took them. Rose made the girl hold her hands while Rose went to the bathroom and, afterward, made the girl flush the toilet. Rose had indicated she had a weapon, but didn’t show one.

The girl, who hadn’t known Rose, clearly had been distraught. She called her parents, who reported the incident to local police, the affidavit said.

Rose was charged with burglary and aggravated criminal trespass, each a Class C felony punishable by up to five years in prison. Misdemeanors included visual sexual aggression against a child, criminal restraint, criminal threatening, theft by unauthorized taking and impersonating a public servant, according an Androscoggin County grand jury indictment.

Prosecutors had sought a mental evaluation to gauge Rose’s competency to stand trial as well as her sanity at the time of the crimes on Aug. 4.

At a hearing in Lewiston District Court last week, Rose was committed to the Riverview Psychiatric Center in Augusta in the custody of the commissioner at the Maine Department of Health and Human Services.

Rose’s commitment stemmed from an agreement between prosecutors and Rose’s attorney. She entered a plea of not criminally responsible by reason of insanity to all nine counts in the the indictment, plus charges of terrorizing and burglary of a motor vehicle from an unrelated case stemming from an incident at a Livermore Falls car lot on Aug. 10, according to court records.

Rose will remain in the custody of the commissioner at Riverview until she is deemed no threat to herself or others, according to Maine law.

Before her April 12 plea, Rose had been held at the Androscoggin County Jail in Auburn on $5,000 cash bail.
