Abstract: Systems and methods for identifying individuals using contraband communications devices in a controlled-environment facility are disclosed. Wireless communications are intercepted using a plurality of access points positioned at different locations within the controlled-environment facility. All wireless communications are blocked in a first group of locations, and individuals assigned to the first group of locations are identified. Some or all wireless communications are allowed in a second group of locations. Individuals are identified as possible contraband sources if they move from the first group of locations to one of the second group of locations after wireless communications are allowed in the second group of locations.
