ST. PAUL - State investigators say a nursing assistant at a St. Louis Park nursing home sexually abused a resident who has dementia.

The report Thursday said Texas Terrace Care Center has suspended the employee and police have referred the case for possible criminal sexual conduct charges.

Home administrator Mat Bedard said the employee has been fired.

The state Health Department said the resident reported that the nursing assistant kissed her on the mouth and touched her sexually in July. Two other residents said the employee had kissed them, with one saying he touched her stomach.

The report said the employee denied the allegations. He was not named.

Bedard said the investigators determined the employee, not the home, was responsible for the abuse and the home's administrators addressed the incident immediately when it was reported.

Four earlier cases of nursing home abuse have been uncovered in Minnesota since August 2008.
