BUCKS COUNTY, Pa. (WHTM) — A Michigan man who helped carry out what prosecutors described as a “violent” comic book store robbery in Pennsylvania was sentenced.

Caleb Simpson, 36, of Michigan, will spend between 10.5 to 25 years in state prison after being sentenced by Common Pleas Judge Stephen A. Corr, the Bucks County District Attorney’s Office said.

Simpson pleaded guilty in March to robbery, conspiracy to commit robbery and aggravated assault, prosecutors said.

The owner of the Comic Collection Store was on a ladder when Simpson and Zackery Tucker, 23, also of Michigan, knocked him off after the duo entered the store Sept. 18, 2022, prosecutors said.

Tucker was already sentenced in March to spend between five and 12 years in state prison for his role in the robbery.

The owner was then tied up while Simpson began hitting him with brass knuckles and threatening him with a knife, the DA’s Office stated. The victim suffered multiple serious injuries that included contusions, broken teeth, ribs and lacerations.

A laptop, cash, comic books, Pokémon cards, action figures and even the victim’s keys were stolen.

Prosecutors said recovered merchandise, DNA and clothing helped investigators to make arrests. The incident was captured on the store’s surveillance video.

Lower Southampton Township Police Department, along with Adrian Township Police Department in Michigan and Pennsylvania State Police, investigated the case.
