The FBI says one man has been arrested in the robbery and killing of an armored truck guard outside a South Florida bank.
The FBI said at a Sunday news conference that investigators believe three other people are still on the loose. FBI special agent John Gillies said those suspects are considered armed and extremely dangerous.
Investigators say 31-year-old Nathaniel Moss was arrested near the Bank of America branch where the Brinks security guard was killed on Friday. Moss has been charged with conspiracy to commit robbery and other counts.
Agents say they have recovered two vehicles used in the robbery, as well as all the money taken. However, investigators won't say how much money had been stolen.
