An Uber driver missing for eight days was found dead inside his vehicle Tuesday in Philadelphia, his family said, making him the second driver for the ride-hailing service to be found in the region within a week.

The body of James Carter Jr. was found in the driver's seat of his 2007 Jeep Liberty outside 30th Street Station, the city's main rail station, his son told Philadelphia's KYW-TV. No foul play was suspected, the report said. It was unclear what caused the death.

Carter, of Willingboro, N.J., was last seen by his family on Feb. 25. He had dropped off a passenger around 5:15 p.m. and then reportedly deactivated the Uber app on his phone a few moments later, the station reported.
