Hundreds of people including law enforcement, local public officials, and the general public gathered near the West Johnson Street Pick N Save grocery store Saturday for a memorial dedication ceremony honoring Wisconsin State Patrol Trooper Trevor Casper who was killed in a shootout with a bank robbery and murder suspect in March of 2015. It was Casper’s first day on the job. State Patrol captain Ryan Chaffee says Trooper Casper followed the suspect’s vehicle as it exited Interstate 41 and traveled east on Johnson Street. “The suspect vehicle turned onto North Berger Parkway and went slowly by the Pick N Save store and did an immediate u-turn and basically opened fire, ambushing Trevor,” Chaffee told WFDL news. “…Trevor was able to exit his vehicle, he had already been mortally wounded, he returned fire killing the suspect.” The event was held at the Trooper Trevor J. Casper Memorial site located in the 100 block of N. Berger Parkway next to the Pick N Save grocery store. Last fall, Pick N Save in cooperation with the Wisconsin Troopers Association, raised over $10,000 for the memorial site. Since then, numerous individuals and businesses have worked toward the development and completion of a memorial bench and flower garden to honor Trooper Casper’s sacrifice.
