ARP, TX (KLTV) - An East Texas man is dead after authorities say his autistic son stabbed him multiple times.
David Adam Wilson, 21, has been charged with the murder of his father David Wayne Wilson.
Authorities say the suspect stabbed Wilson with a kitchen knife.
Tuesday, family members said they had been seeking medical help for the 21-year-old, and the tragedy could have been avoided.
Handcuffed by authorities, Adam Wilson was arrested for the murder of his father. Family members are shocked by the actions of the autistic 21-year-old.
"There was no way of us knowing, although his behavior was drastically different," said Angela Sanderson, the victim's sister.
"It's apparent that he retrieved a kitchen type knife, stabbed his dad multiple times in the upper body, and his dad died at the scene," said Lt. Tony Dana, with the Smith County Sheriff's Department.
Investigators were at the scene all day. When sheriff's deputies arrived Monday evening, they said they found the 21-year-old hiding inside a storage unit to the side of the house.
"He was in a very confused type state," said Dana. "He was angry. Obviously, he had made threats to family members earlier in the day."
But, family members and neighbors say this type of aggression was uncommon in Adam.
"I had tears in my eyes," said Walter Ritch, a neighbor. "It just shocked me...He's a really, really good guy. Shy. But kind at heart."
"I don't want this to characterize a whole group of people," said Sanderson. "Adam was autistic, and this was not autism. Whatever has happened is a result of what the family has been trying to get some help with in the last few days."
The family says Adam's behavior had changed. He became agitated and aggressive in the past few weeks. They took him to the emergency room over the weekend and the doctor on Monday.
"[They were] begging for help, asking for someone to take some time and evaluate," said Sanderson.
Shortly after the doctors visit, Adam went back to his father's house and that is when the stabbing took place. It is a tragedy, the family was trying to prevent.
Adam Wilson is being held in the Smith County Jail on a $500,000 bond.
The Smith County Sheriff's Department says this is the second stabbing death in the county this month.
