Authorities have released the name of the man killed while crossing I-215 Saturday night.

Killed was:

James Michael Summers, 49, San Diego.

Summers apparently was passing through Salt Lake City when he was hit and killed on I-215 near 2200 North by a vehicle traveling in the right southbound lane, Utah Highway Patrol trooper Travis Shirley said.

Summers didn't have a car and is presumed to have been hitchhiking back to California from an unknown location. "We believe he was a transient," Shirley said.
