Many victims never had the opportunity to celebrate Christmas.
Some of the presents waiting beneath the tree would never be opened.
For investigators, that image became one of the most haunting details of the entire case.
A decorated Christmas tree.
Wrapped gifts.
And a family gathering that never happened.
The Shockwaves Continue

Days later, additional incidents occurred in the nearby community, leaving more victims and sending shockwaves throughout the region.
When authorities finally confronted Simmons, they were surprised by his reaction.
