The driver of a pickup truck failed to slow down for traffic on Interstate 97 in Anne Arundel County and hit a 2000 black Honda Accord just before 4 p.m. Friday, killing the Honda's driver, according to Maryland State Police.

He was identified by police Saturday as 49-year-old Stephen T. Patterson of Hampstead.

The accident caused the southbound lanes of I-97 to be closed for three hours.

Police said 29-year-old Daniel Martin Harris of Worton, who was driving a 2003 green Ford F-250, failed to slow down on the southbound side of the highway at the spur to eastbound U.S. Route 50 and collided with the Honda. The Honda then struck the rear of a 2003 red Cadillac CTS.

The Honda driver was pronounced dead at Anne Arundel Medical Center.
