Two Men Killed in Rollover Crash

Two men were killed and another was injured in a car accident early yesterday on Pennsylvania Avenue just north of the Capital Beltway, Prince George's County police said.

Police said a Land Rover traveling north on Pennsylvania Avenue at 3:15 a.m. went over an embankment and flipped several times.

The 33-year-old driver and a 34-year-old passenger in the front seat died. A 33-year-old passenger in the back seat was treated at a hospital for minor injuries and released.

"We are looking into the possibility of speed as a factor," said Cpl. Diane Richardson, a Prince George's police spokeswoman. She said it appears that the two men who died weren't wearing seat belts. Police were not releasing the names of the victims until families had been notified.

ALEXANDRIA

Man Steps in Front of Train

A 44-year-old Arlington County man was killed Friday when he threw himself in front of a freight train in Alexandria. The incident held up freight and Virginia Railway Express trains in both directions for more than three hours during the evening rush, authorities said.

Shortly before 4 p.m., Stephen Patrick ran in front of a northbound Norfolk Southern freight train as it came out of the tunnel under Duke Street near the 100 block of Callahan Drive, police said. The site is about 500 yards south of the VRE and Amtrak station in Alexandria, police said.

Southbound commuter trains resumed service about two hours after the incident. Northbound tracks were reopened about 7 p.m.
