The sisters say they began to wonder if money had been the motive for their mother's shooting.

But without police action, they felt they had to move on.

So I kind of started letting it go.

Chelsea says she even let her son Greg build a bond with his grandfather.

I hated him for taking my mom from me, but I loved how good he was to my son.

Four years later, in 2020, Corporal Greg Allen was assigned to investigate open cases for the Pennsylvania State Police and says this case caught his eye.

What about this case stood out to you?

When questioned, Bruno quickly changed his story.

He also offered this version.

Bruno knew his way around guns, says Corporal Allen.

So why would he have his finger on the trigger of a gun that was loaded?

Crime Unit Supervisor Corporal Dan Nylon was asked by Corporal Allen to examine all the evidence, beginning with Bruno's police interview.

To begin with, says Corporal Nylon, if Bruno was really trying to clear the gun's chamber, he would have ejected the magazine.

There were also two safeties on the gun.

Corporal Nylon showed us just how hard it is to discharge the weapon accidentally.

There were also questions about where Bruno and Melissa were sitting when the fatal shot was fired.

But Nylon and Allen say there was blood and ballistics evidence on the wall behind Bruno.

So the evidence is here and here.

But he says he shot this way.

Correct.
