A Topeka police officer on May 5, 1912, was staked out at the Union Pacific train station. Caswell S. Matthews was under orders to wait for two people suspected of holding up the city marshal in Bonner Springs several days earlier.
The pair were thought to be en route on a train to the capital city from Bonner Springs. Matthews eyed two suspicious people shortly before 6 p.m. who were crossing the tracks in front of the depot. The officer confronted them.
