A computer-implemented criminal intelligence gathering system adapted to be deployed within a confinement facility. The system comprises target devices installed at strategic locations within a prison. A target device comprises a microphone for capturing auditory information, a compression module for eliminating periods of silence from the auditory information resulting in the generation of a compressed auditory information, a segment module for segmenting the compressed auditory information and a stamp module time-stamping each segment. The system further comprises a database listed with a plurality of target entries, each of which representing a target device. The database is configured to receive the segmented auditory information from at least one target device at a time such that, the received auditory information is associated with the corresponding target entry. The system further comprises a user interface for enabling remote retrieval of a segment stored within the database based on date, time and location.
