CRYSTAL FALLS - Autopsy results and DNA evidence were the main topics of discussion on day four of the murder trial against David Anthony Levack.
Levack, 45, of Kingsford faces felony counts of open murder, felony murder, home invasion, and witness intimidation for allegedly killing 81-year-old Joyce Johnson of Stambaugh Township before she could testify against him in a stolen property trial on Sept. 27, 2011.
Dr. George Krzymowski of Marquette General Hospital performed the autopsy on Johnson's body on Sept. 28, 2011.
He testified that there is a certain bone in the human neck that is difficult to break. It is only connected to soft tissue, and it can move if pressure is placed on it from one direction. In order to break the bone, there has to be a squeezing or crushing force applied to the neck, he said.
Dr. Krzymowski testified that that particular bone in Johnson's neck was broken into two pieces. Also, there were several bruises on Johnson's neck and jaw line.
"The cause of death was manual strangulation," he said. "The manner of death was homicide."
