FORESTVILLE, Md. (AP) -- Maryland State police say a woman and her teenage son were killed when their car crashed into the back of a tractor-trailer on Interstate 495.
Troopers say 39-year-old Toykia Kenya Keys of Fort Washington was driving north on the outer loop in Forestville about 1 a.m. Monday. Police say Keys drove into the back of a tractor-trailer traveling the same way.
Keys and her 14-year-old son, Kamany Love, were pronounced dead at the scene. The driver of the tractor-trailer was not hurt.
Authorities say speed and aggressive driving by Keys may have been factors in the crash, which is under investigation.
