Some escapees were tracked down through their personal interests. Gary Morehead, who worked as the chief of security at Gold Base in the 1990s, cites the example of a senior executive who fled in 1992. The executive was known to be a baseball fan. A week later, Morehead caught him in the parking lot of the San Francisco Giants stadium. If all else failed, according to Morehead, the homes of the blown member's friends and family were staked out by Scientologists using scanners to listen in on cordless phones and cell phones, and tracing the license plates of any vehicles that turned up.
