A California man has been charged with the rape of a mentally-disabled patient at a nursing home last year, after the woman gave birth to a baby whose DNA matched his, police said.

FOX40 reports that Marquise Montgomery, 22, was arrested on charges of rape early Thursday in Sacramento and remains jailed on $150,000 bail.

Investigators had to wait until the child was born earlier this year to conduct DNA testing to identify the father. Once the results were returned, authorities had to compare them to samples from men who worked at Casa Del Mar Care Facility in Penryn at the time. Montgomery was later identified as a potential suspect, the station reports.

The victim, who is severely handicapped and legally blind, was roughly six months pregnant in late 2011 when authorities were summoned to investigate.
