A 10-year-old repeatedly shot his older sister and then killed himself at their rural home near Huntsville, Texas.
Their mom heard the gunfire upstairs and rushed down to her daughter's room to find her son's body and her daughter still clinging to life. Their dad was at work.
"You never expect something like that," neighbor Andrew Thompson said.
The gunfire erupted right around bedtime Thursday. The 15-year-old girl was in bed at 9 p.m. when her brother barged into her room, pointing a handgun at her, investigators said.
"He walked into the 15-year-old's room and discharged the weapon several times in the direction of his sister," Walker County Sheriff's Detective Gregory Williams said.
She was shot several times, but she survived. Investigators said the boy turned the gun on himself and pulled the trigger. He was taken to a hospital and later pronounced dead.
"The firearms in the house were locked up in a safe. The 10-year-old accessed the code and got the firearm," Williams said.
Neighbors said the brother and sister were always playing together outside. Only five families live on that small country road, so they all know one another.
"They come to church with me. It's scary, you know," Thompson said.
What would make a 10-year-old do such a thing? Did he suffer psychological issues? Did the siblings argue? There are far more questions than answers.
"I haven't talked to the 15-year-old yet," Williams said. "She was in surgery until early this morning. She's not in the condition to talk right now."
Investigators said they plan to give the family a couple of days to grieve before interviewing them. The girl is in critical but stable condition in the hospital.
Investigators do not expect the parents to be charged because the gun was locked away.
"It's in God's hands right now. That's all we can do," Thompson said.
