SHERMAN,TX -- A Grayson County jury convicted Robert Gray Jr. this morning of murder with a sentence of 90 years in prison.
Prosecutors say a 911 call, made by Robert Gray Jr. was a key piece of evidence that helped the jury convict him of murder.
911 Dispatch: Dennis 911?
Robert Gray: Hi how are you? I think my son stopped breathing.
Thursday, a Grayson County jury found Gray guilty of murdering 15-year-old Brandon White, his ex-girlfriend, Holly White's disabled son.
The same jury recommended a sentence of 90 years in prison.
Assistant District Attorney Britton Brooks says he wanted justice for Brandon.
"In this case, he had no way to defend himself from Robert Gray," said Brooks.
EMT's found Brandon dead at a Denison home on January 8th 2013.
When they responded to Gray's 911 call.
Gray said Brandon wasn't breathing, but prosecutors claimed, Brandon had been dead an hour before that call.
Assistant District Attorney Matt Johnson says the evidence showed that Gray and Brandon's mother would hog tie and gag Brandon, because of his autism and seizure related behaviors.
The medical examiner testified that Brandon's death was a homicide and he died of Positional Asphyxiation.
Prosecutors say before bed that night, Gray had beaten Brandon, put a pillow over his face to quiet him and the teen suffocated.
Following the guilty verdict, the defense stated they will file a motion on Monday for a new trial.
Gray must serve 45 years before he is eligible for parole.
"You can't bring Brandon back, but you can send a message out there to all the bullies," said Assistant District Attorney Matt Johnson.
