On the evening of April 2, 2014, 36-year-old Robert J. Blanchard was found dead from a gunshot wound in his Afton, Tennessee, home. Investigators quickly focused on his 16-year-old son, Zachary Blanchard, as a person of interest; friends of the family described the father-son relationship as strained.

In the days after the shooting, Zachary left the area with three other teenagers — 15-year-old Liam Lawler, 15-year-old Daniel Richards-Birchfield, and 16-year-old Shelby Riley. The four were located in South Carolina and led officers on a vehicle pursuit that ended when spike strips disabled their van. After a short foot chase they were taken into custody and searches recovered multiple stolen firearms.

Zachary Blanchard was charged with first-degree murder of his father. Lawler, Richards-Birchfield, and Riley were charged with being accessories after the fact to first-degree murder and with theft. The teens were held in a South Carolina juvenile facility before being moved toward extradition to Tennessee.

Does anyone have information about Robert Blanchard, the youths involved, or the strained relationship that might shed light on what happened?
