A Woodbridge woman has been accused of killing her 82-year-old father.

Patricia Blevins, 53, was charged Friday with murdering her father, Marden Wilson, Prince William County Police said Monday.

Marden Wilson died at Potomac Hospital, where he was taken after collapsing, on March 13. A toxicology report found that he had a high level of Sertraline, a prescription anti-depressant and anti-anxiety drug, in his system.

Police said Patricia Blevins became a suspect when authorities learned she was under investigation for prescription fraud, including Sertraline.

Patricia Blevins is being held without bond.
