A former Minnesota nursing home employee who raped an 83-year-old resident with dementia was sentenced to eight years in prison last week, one year longer than prosecutors originally sought.

George Sumo Kpingbah, 77, was sentenced Thursday by Hennepin County District Judge Elizabeth Cutter, who said she pursued a sentence longer than that requested by prosecutors because Kpingbah had “violated a position of trust” at the nursing home where he worked as an aide.

“This [rape] affects everyone who has to place a loved one in a facility,” Cutter told the courtroom, according to the Star Tribune.

A Department of Health investigation found the facility, Walker Methodist Health Center in Minneapolis, not responsible for the December 2014 incident since Kpingbah had already taken a course on preventing abuse and the facility was properly staffed on the night of the incident.

In September, Kpingbah agreed in a separate civil settlement to pay $15 million to the estate of the rape victim if he is ever convicted of criminal sexual assault again, or found liable for abuse or neglect of a vulnerable adult once he is released from prison. The massive fine is an attempt to deter Kpingbah from committing another assault upon release, attorneys said at the time.
