KANSAS CITY, Mo. — At 7:37 a.m. Sunday, the Johnson County Public Safety scanner traffic channel first mentioned the events that led to a deadly police shooting.

Just a little more than half an hour separated the report of a vehicle theft at the QuikTrip at 95th Street and Interstate 35 in Lenexa and the scene being secured at the 4700 Lamar Ave. QuikTrip in Mission.

Fairway Police Department Ofc. Jonah Oswald and suspect Shannon Wayne Marshall were killed after an exchange of gunfire at the Mission QuikTrip.

KSHB 41 is choosing to report on select portions of the scanner traffic out of respect for the officer and his law enforcement co-workers.
