Police have issued an Amber Alert for a 9-year-old girl who they believe is may be in the trunk of a sport utility vehicle with her mother after being carjacked in suburban Philadelphia.

The carjacking happened Tuesday afternoon following an accident in Upper Southampton Township, Bucks County.

A 38-year-old Feasterville woman, Bonnie Sweeten, called 911 later Tuesday afternoon and said she was the victim of that carjacking. Sweeten told a dispatcher that she and her 9-year-old daughter, Julia Rakoczy, were in the trunk of a Cadillac. That call was traced to a cell phone tower in downtown Philadelphia.

Authorities are looking for Sweeten's gold or silver GMC Yukon Denali, which has Pennsylvania license plate GYK-8998. They're also looking for a black 1990s Cadillac.
