BUCKS COUNTY (CBS) — A Bucks County home health care aide has been charged with stealing tens of thousands of dollars from an elderly Warminster Township woman over a 13-month period.

Bucks County Assistant DA Kate Byrne said 47-year-old Lisa Ann Lehmann-Waters, a private-duty home health aide, used a debit card and wrote several checks to herself while working for a 78-year-old woman from March 2015 until April 2016.
