Milam appeared in federal court Thursday in Gulfport to face 11 counts of bank robbery. The 44-year-old Milam, of Tyler, Texas, was denied bond by U.S. Magistrate Judge Robert H. Walker.
Each bank robbery charge carries a penalty of up to 25 years in prison and a $250,000 fine.
Afterward, Milam was turned over to U.S. Marshals to await extradition back to Richardson, Texas. Authorities would not disclose where he was being held.
Milam was arrested Tuesday after Jackson County Sheriff Mike Byrd shot out a tire on his vehicle during a westbound, high-speed chase on Interstate 10. Milam was wanted in Texas for shooting at officers during a New Year's Eve robbery of a Richardson bank.
