3 defendants missing from Illinois lockup

ULLIN -- A manhunt is under way for three federal prisoners who bolted from a detention center near the southern Illinois town of Ullin.

The U.S. Marshals Service isn't saying how the three men on Wednesday managed to make their way out of the Tri-County Detention Center in Pulaski County.

Marshals say the men are considered armed and dangerous.

Among the missing men is 35-year-old Rodney Brown of Alton, who was being held on a weapons charge. Twenty-eight-year-old drug defendant Thomas Glaab of Anna and 35-year-old accused illegal immigrant Miguel Robles-Moya of Chicago also are missing.
