Vance requests that the team take over murder investigation from Metro PD of Colonel Peyton when his body was found two weeks ago after suffering multiple axe wounds.
Overwhelming evidence points to Parks' 18-year-old son, Nick Peyton, who is adamant about his innocence.
Unfortunately, unless the team can secure a conviction, the son walks. Gibbs and the team use various methods of interrogation until finally Nick confesses to the murder.
However, Gibbs soon suspects that Nick may not be the killer.
Upon further investigation he discovers that Nick’s estranged mother came back wanting to be a part of the family again.
