This Monday, deputies detained a 69-year-old man accused of killing his wife by strangulation.

The Iredell County Sheriff’s Office was called to the Iredell Memorial Hospital emergency department on Monday, Nov. 13, at approximately 2:30 a.m., regarding an “elderly female victim of an assault.” Deputies arrived at the scene and learned that the woman was taken to the hospital by her husband, Clarence Tyson. Rebecca Tyson was given life-saving treatments by medical personnel, but she eventually passed away from her wounds.

During Clarence Tyson’s interrogation with deputies, it was discovered that the two had gotten into a domestic fight at their residence. After that, authorities proceeded with their investigation to the couple’s home at 141 West Iredell Circle.

Following an autopsy on Tuesday, Nov. 14, the Chief Medical Examiner’s Office determined that Rebecca Tyson’s cause of death was strangulation. In addition, she suffered many fractured bones and bruises from the assault, which were further serious injuries. Detectives from the sheriff’s office charged Clarence Tyson with first-degree murder after learning the results of the autopsy. He’s still detained without bond.

Tyson’s criminal history includes prior accusations of felony employee larceny, assault on a female, and driving under the influence, according to WJZY-TV.
