St Joe police believe at least two groups are responsible for a rash of thefts of catalytic converters from cars. Within the last week or so there have been five such thefts reported at Lafayette High School, four at Heartland Hospital, four at American Family Insurance, and two at Menards.

All of the thefts occured during business hours.

Police say the devices are stolen and resold, or the precious metals inside are sold for scrap.

Thieves are targeting General Motors products, including Pontiac Grand Ams and Sunfires.

Authorities are seeking two black men driving a grey four-door sedan at the Heartland Business Plaza on the North Belt. Police believe the men might be linked to the thefts. Other witnesses described a group of two white men in a blue Mercury Sable, driven by a white woman.
