SOMERSET COUNTY (KDKA) — A missing woman was found dead in a Somerset County lake on Saturday night.

Pennsylvania State Police reported Sunday that 63-year-old Cathleen Augustine, of Lemont Furnace, Pa., was found dead around 7:30 p.m. Saturday at the Yough Lake Marina.

According to state police, Augustine was found inside her vehicle, which was completely submerged in the lake.

Augustine was reported missing Friday. The woman’s sister told police she hadn’t heard from Augustine since 6 p.m. Wednesday.

“She hadn’t gone in to work and since she was taking care of my grandfather, she hadn’t been home, which is extremely unlike her,” Augustine’s son, Ricky DiMarco, Jr., said. “She’s a very responsible person.”

A dock worker found Augustine’s purse, cell phone and personal mail at the Yough Lake Marina, which led police to search the area and ultimately discover Augustine’s car in the lake.

Investigators say there is no indication of foul play, but the case is not yet closed.

“The circumstances involved seem odd because she wasn’t depressed or upset,” DiMarco said. “She wasn’t that type of woman. She was always very positive.”

DiMarco hopes someone saw Augustine before her death and will come forward with information.

State police say the investigation is ongoing.
