A Texas resident has been sentenced to several decades in prison following a horrific crime involving the murder of his mother in their shared home.
Brian Keith Griffin, 37, admitted guilt on a murder charge last Thursday, as documented by Harrison County court records.
In a swift court decision, 71st Judicial District Judge Brad Morin handed Griffin a 30-year prison sentence for the deadly stabbing of his 55-year-old mother, Tammy Bogue, in November 2024.
The tragic event took place at the family apartment located on Norwood Street in Marshall, Texas, a small city positioned about 40 miles west of Shreveport, Louisiana.
On November 27, 2024, shortly before 12:45 p.m., Griffin made a 911 call to report his actions, according to court records reviewed by The Marshall News Messenger.
Responding officers found Bogue on the floor suffering from multiple knife wounds. The victim was pronounced dead at the scene of the crime, according to a press release issued by the Marshall Police Department. Her killer’s culpability was apparently never in doubt.
“During the custodial interview, Griffin admitted to stabbing his mother multiple times intending to kill her,” police wrote in a probable cause statement attached to the charging document.
During his sentencing hearing, Griffin said he had repeatedly been treated for mental illness – once due to a suicide attempt – but admitted he was not insane on the day of the murder. His defense attorney noted he was found competent to stand trial.
“It was going to be a battle of the experts,” Harrison County District Attorney Reid McCain told the Messenger, explaining what would have likely occurred during a trial had the parties not agreed to a plea deal.
Had he gone to trial, the defendant faced a possible sentence of up to 99 years in prison. The defendant, the state, and the surviving family agreed on foregoing such proceedings and a lesser sentence.
“I had a really good family,” the prosecutor told the newspaper. “They were easy to work with. I think they love him, but also know that he needs to be held accountable. So we had multiple conversations, and they were fine with the 30-to-40 (year) range.”
One family member, however, seemed to reject the since-condemned man’s narrative about his mental health issues.
Bogue’s sister reportedly said Griffin should have been taking his medication if he wanted to blame the violence on mental illness.
“This was not a tragedy,” the slain woman’s sister said. “It was a betrayal of trust to our family. She deserved to live, deserved to grow old…to love and be loved. We not only lost one family member that day. We lost two. And like you told (the investigators) ‘She had to go.’ Our final words to you, Brian: ‘Now you have to go.’”
