A car was found in a Philadelphia river Thursday during a massive search for a missing mom who was last seen leaving a party more than two weeks ago and hasn't been heard from since.

Toni Lee Sharpless, 29, a nurse and the mother of a 12-year-old girl, vanished on Aug. 23 after leaving a party at about 5 a.m., MyFOXPhilly.com reported.

It wasn't immediately known whether the car discovered in the Schuylkill River by crews from Texas EquuSearch is hers. Dive teams were headed to the site. She was driving a black 2002 Pontiac Grand Prix, license plate number DND-7772, the night she was last seen.

Sharpless, of West Brandywine, Pa., disappeared in Lower Merion after leaving a party with a friend.

The two got into an argument, and the friend got out of the car, MyFOXPhilly.com reported. Sharpless drove off and hasn't been seen since.

Sharpless' cell phone hasn't been used and investigators have thus far found no signs of her.

Her family has said she went to Ice Nightclub in King of Prussia and then to G Lounge in Philadelphia before heading to the house party in Gladwyne with her friend.

Sharpless is described as 5 feet 5 inches tall, 135 pounds, with red hair and blue eyes.
