A retired Marine working as a clerk at a Florida GameStop store has been charged with manslaughter after police said he fatally shot a shoplifter who tried to steal $600 worth of Pokemon trading cards.

Derrick Guerrero, 33, was working a shift at the video game retailer in a suburban Fort Lauderdale strip mall Tuesday night when a shoplifter grabbed five boxes of Pokemon Scarlet & Violet “ultra-premium” cards and ran for the exit, Pembroke Pines police said in a report released Wednesday.

The cards, based on the popular Japanese media franchise, retail for $120 a box.

Guerrero pulled a handgun from his waistband and fired one shot, hitting the shoplifter in the side, police said.

The victim dropped the stolen cards and ran outside to a waiting pickup truck, where his girlfriend called police.

He died three hours later at a hospital.

The victim’s family identified him to NBC 6 as 21-year-old Chadrick Coats.

His grandmother said Coats was a “good kid” and a sophomore at Florida Memorial University.

Police said store security cameras showed that Coats never threatened Guerrero nor brandished any weapons.

During Guerrerro’s initial court appearance Wednesday, his attorney said that he had been honorably discharged from the US Marine Corps after 10 years of service and was working as an assistant manager at GameStop to provide for his wife and two young daughters.

Guerrero had been the victim of a robbery at work on September 11 and had bought the gun for his personal protection, police said.

A judge set Guerrero’s bond at $25,000 and ordered him to wear a GPS monitor if he posts bail.
