Chilling Video Shows Moment Man Fatally Shot His Brother Before Setting Fire to Home

Weber County investigators released terrifying Ring camera footage -- as well as body cam footage from one of the responding officers -- on Thursday from the April 27 incident, showing the moments Jeffrey Roberts showed up to brother Scott Roberts' Utah home.

Due to the graphic nature of the footage, the video below is age-restricted and must be viewed on YouTube.com.

After ringing the doorbell, Jeffrey calmly tells his brother he's there to see their mother. After being told she was in Missouri -- and had been for about a year -- Jeffrey then pulls out the handgun and begins firing.

As neighbors called 9-1-1, Roberts can be seen going in and out of the house while talking to someone on his phone. At one point, he's pictured holding a shotgun, as well as a large bag. He also tells someone on the other end of the phone to "empty my bank accounts, quick as you can."

During the attack, Scott's wife, Jodi, was also shot -- though she survived. According to police, Roberts then used road flares to start a fire inside the house.

By the time police arrived at the scene, the blaze was already roaring out of one of the home's windows, while smoke billowed from the open front door. The Weber County attorney's office said Roberts began shooting at authorities surrounding the home -- and can be seen in doorbell footage firing toward the street. During the shootout, he was shot in the head and killed.

The incident is still under investigation.

In a GoFundMe post, Scott and Jodi's daughter said, "My mom is alive because my dad fought my uncle and told my mom to run. Knowing that my dad died a hero is bringing us a small bit of comfort."

She also said Jeffrey had been "estranged" from the family.
