SHAWNEE, Kan. — The Shawnee business where a gun shop owner lost his life is selling memorial T-shirts in his honor.

The front of the shirt reads ‘the ultimate price.’ The back of the shirt lists the name of the store. It also says ‘always remember, be proud, be prepared, be free.’

The shirts go on sale Sunday for $20.

They can be picked up in one of the classrooms at ‘She`s A Pistol.’

Four men walked into gun shop and tried to rob it last month.

Jon Bieker died protecting his wife and his business during a shootout with the suspects.

Three of those suspects have been charged with first degree murder.

The fourth man is still in the hospital.
