A Des Moines man is accused of sexually abusing a woman who lives in a care facility where the man worked. Des Moines Police spokesperson Sergeant Lori Lavorato says 41-year-old Napoleon Mbonyunkiza was arrested Monday – three weeks after it was discovered that a resident of Mosaic was pregnant.

“This client was 32-year-old at the time, is wheelchair bound, has no means of communication and suffers from cerebral palsy,” Lavorato said. The pregnancy was terminated at 22 weeks.

Lavorato says around 25 male staff workers at Mosaic provided D.N.A. samples. The D.N.A. from the child matched that of Mbonyunkiza. He is charged with third-degree sexual abuse, neglect of a dependent person and dependent adult abuse.

Mosaic is a faith-based nonprofit organization which serves around 180 adults in more than 40 locations. The Iowa Department of Inspections and Appeals is helping police investigate the case.
