Meigs County District Attorney General Russell Johnson says the Tennessee Highway Patrol has retrieved recording devices from a deputy’s vehicle that went into the river last week.

The incident took the lives of Meigs County Deputy R.J. Leonard and Tabitha Smith.

Deputy Leonard was transporting Smith to jail when he accidentally ran off a boat dock at nighttime and into the Tennessee River.

Authorities recovered their bodies.

Johnson said yesterday a Tennessee Highway Patrol sergeant with the critical incident response team pulled the digital recording devices from the engine control module (ECM).

An ECM is a device that controls multiple systems of an internal combustion engine in a single unit.

Johnson says it should give information about speed and braking.

The car was submerged. Johnson says the highway patrol is exploring options to get the devices dried out in hopes of recovering information.
