Early in January, FOX13 reported Lawler hired Jeff Rosenblurm to investigate the claim that his son committed suicide in a Hardeman County Jail.
He was hired by the Lawler family "to pursue a civil rights claim against Hardeman County, and the deputies that were supposed to protect Brian Christopher Lawler."
Attorneys for his estate issued subpoenas to both the Hardeman County Sheriff's Office and the Tennesse Bureau of Investigation.
The subpoenas are part of a civil action by the Lawler family.
