PLOT
Lone Star Justice is a new Investigation Discovery series highlighting the successful homicide cases of top detectives with the Smith County Sheriff's Office.

Luckily, this East Texas county has a detective squad with a history of solving major crimes at a rate 20% higher than the national average. A team of three retired investigators - Sheriff J.B.
