Placer County sheriff's officials are continuing DNA screening in an effort to identify the person who impregnated a severely mentally and physically disabled woman living at a Penryn care home.
The 34-year-old woman was discovered in December to be about six months pregnant after undergoing an ultrasound test and has since given birth. The woman is mentally disabled, legally blind and unable to feed or care for herself.
Placer County sheriff's spokesman Lt. Mark Reed said investigators have been collecting DNA samples from men the woman is believed to have had contact with in an effort to find a match with the baby's DNA.
"We're still looking to collect some more samples," he said. "It's a big list. We're clearing people as we can."
The Bee is not identifying the care facility or the woman because of the sensitive nature of the case.
Ralph Montano, a spokesman for the California Department of Public Health, said the facility is the subject of an ongoing investigation by the department and for that reason he could not discuss details of the case.
