Police Chief's Son Among Two Officers Killed in Shootout in West Memphis, Ark.

WEST MEMPHIS, Ark. (CBS/AP) Two West Memphis police officers were shot and killed Thursday, including the son of the police chief, during a traffic stop along a busy cross-country interstate highway. The slain officers were Brandon Paudert, the chief's son, and Bill Evans.

The younger Paudert was assigned to the drug unit but it wasn't immediately known why the officers pulled over a white van with Ohio plates.

After the two officers were killed, the two suspects were also shot dead, in an exchange of gunfire that left the local sheriff and his chief deputy wounded.

At a news conference outside a Memphis, Tenn., hospital, a spokesman said Crittenden County Sheriff Richard Busby and his chief deputy, W.A. Wren were wounded.

Busby and Wren shot and killed the suspects in a Wal-Mart parking lot near the intersection of Interstates 40 and 55 in West Memphis, Ark. Both highways are major cross-country interstates.
