According to police, Walker had been drinking before he crossed the southbound lanes of Route 141 and was waiting to cross the northbound lanes when he was hit. The crash knocked him into the southbound lanes, where he was hit by a second vehicle. That driver, 23-year-old Rachel Crowe of New Castle, called police.
Walker was taken to Christiana Hospital in critical condition and died Thursday.
Police are still looking for the first driver.
