A gang of thieves treated the Cash Cow check-cashing company as their own cash cow, making off with more than $500,000 from ATMs over the past year, police said Thursday. Two of the thieves were caught fleeing early Sunday from a Cash Cow office in Slidell, Sgt. Daniel Seuzeneau said Thursday. The ring has struck nearly 100 times in and around New Orleans over the past year, frequently targeting the Cash Cow company and sometimes returning several times to the same location. The thieves would first trigger the alarm system and watch police respond, Seuzeneau said.
