Gregory Hayes, 47, killed in motorcycle crash with drunk driver on May 9.

A police officer for the School District of Philadelphia died in Upper Darby on his way to work Friday night when his motorcycle collided with a pickup truck driven by a drunken driver.

Gregory Hayes, 47, of Landsdowne, was heading east on his Suzuki motorcycle on Marshall Road at 11:15 p.m., said Michael Chitwood, superintendent of Upper Darby police.

A pickup driven west on Marshall at high speed by Salome Seay, 32, of Upper Darby, made a sudden left turn at Coverly Road in front of the motorcycle, Chitwood said. He characterized Seay's driving as "aggressive."

Hayes tried to brake but could not stop in time, Chitwood said. The motorcycle hit the side of the truck and the impact propelled Hayes from the motorcycle seat, Chitwood said. He said Hayes, who was wearing a helmet, died instantly.
