CHEYENNE, Wyo. (AP) - A church van ran over an injured motorcyclist and a man who had stopped to help him, killing both, police said Monday.

The accident happened Sunday night on U.S. 85, about 30 miles north of Cheyenne, according to Highway Patrol Sgt. Stephen Townsend.

Jeffrey A. Lingwall, 40, of Scottsbluff, Neb., was riding a motorcycle northbound when he hit a deer and crashed, landing in the northbound lane.

Stephen M. Thompson, 48, of Cheyenne, who was traveling south, stopped to help. He was standing next to Lingwall when a northbound van driven by Sylvia F. Burmeister, 46, of Scottsbluff, struck both men, Townsend said.

Lingwall and Thompson both died at the scene.

The van had five juvenile passengers and was one of three vehicles transporting a church youth group from Scottsbluff, Thompson said.

The crash remained under investigation.
