Q: So Tony, can you just talk a little bit about Deputy Warden Teagues and what that case was and what it resulted in recently?
The Teed case began with a missing officer in 1934 and unfolded into a decades-long investigation that was rekindled by a single informant's tip, leading to the identification of the shooter and closure that finally recognized the officer down, though prosecution did not occur for everyone involved due to ages and circumstances at the time.
