A Utah father's long-awaited reunion with his four children has been tragically cut short. The children were victims of a heinous crime, and their grandmother is accused of being responsible.

The father, Brady Harmon, had been engaged in a years-long visitation battle and was finally set to see his children. He was scheduled to pick them up on a Wednesday, but instead learned of their tragic fate.

Further details about this incident are available from NBC 5 Dallas-Fort Worth, including the circumstances surrounding the crime and the visitation battle.
