SAN ANTONIO (AP) – Two former officials of a San Antonio military medical center have pleaded guilty to their roles in a fraudulent scheme involving more than $7 million in military contracts.

Federal prosecutors say retired Army Master Sgt. Lawrence Peter Fenti of New Braunfels and Dr. Heidi L. Webster of Manhattan, Kan., each pleaded guilty Thursday to one count of conspiracy and one count of bribery.

The 43-year-old Fenti was the chief administrator for Brooke Army Medical Center’s radiology department and the 50-year-old Webster worked at the center.

Prosecutors say they steered contracts to two Kansas companies run by Webster that she registered as defense contractors.

They each face six years in prison. Prosecutors seized about $500,000 in the investigation and are seeking restitution of $400,000 from Fenti and about $600,000 from Webster.
