A Bossier Parish man who Shreveport police detectives had been searching for is now behind bars. Last Friday, investigators obtained an arrest warrant for 22-year-old Quinten Marshall, charging him with one count of armed robbery of the Global Express store in the 500 block of East Kings Highway. Marshall surrendered himself to authorities yesterday. His bond is set at $75,000. Marshall is the second suspect arrested for this robbery. Last week, 22-year-old Darrius Ivy was booked into the Shreveport City Jail for his alleged role in the crime.
