Ty Bradley was a cleaning and maintenance worker who worked on Monument Island when others would not in BioShock Infinite. Voxophones left behind by Bradley express concern about the restricted parts of the Monument Island, mentioning how others are scared by the "thing" locked upstairs.
Three months after his employment, Ty makes a recording to his superior, R. Thompson, noting some singularities occurring around the complex. Due to the abrupt ending to his recordings, he may have become a victim of one of those incidents.
