SHELBY COUNTY, TX (KTRE) - Bernard Metcalf showed up at his neighbor's house first finding Smith's mother, 37-year-old Vicky Lynn Dean dead in a pickup truck.
He called 911.
"It's the hardest thing that, you hear of it like I say on TV or somewhere, but you don't ever think it will happen that close to you, you know," Metcalf said.
For 30 years, he's lived next door to the Deans.
"Richard would do anything in the world for you," Metcalf said. "Richard was good. I don't know what make him do what he done."
Johnson said deputies were called to a property on State Highway 147, just outside of Shelbyville around 6 p.m.
When deputies arrived, they found Vicky Lynn Dean, 37, in a pickup, dead from an apparent shotgun wound to the face. Johnson said it appeared she was trying to leave the property.
Her son Christopher Reagan Smith, 20, was found dead in a small building outside the house, Johnson said.
Johnson said while deputies were on the scene, the San Augustine Sheriff's Department contacted them and said Dean's husband, Richard Vaughn Dean, 38, turned himself in and confessed to killing his wife and stepson.
They also say Dean had his 8-year-old son with him when he turned himself in, but there is no evidence that the child witnessed the shootings.
Richard Dean has been charged with capital murder and is in the Shelby County Jail after a judge declined to set a bail. So far, investigators have not determined a motive in this shooting. Dean's 8-year-old son is now staying with family friends.
Richard Dean has previous convictions for aggravated assault and burglary on his criminal record.
"I don't know, just lost our neighbors is all," Metcalf said.
The boy is staying with friends of the family, while his dad is jailed for capital murder.
"I can't describe the feeling that I had after I seen her in that truck," Metcalf said. "Never experienced and I hope to goodness I never do again."
