I was in Detroit on Wednesday, and as I passed the airport newsstand, I did a double-take when I saw the headline in the Detroit Free Press. “Grandma Guilty of Murder,” it read: “Teen’s 911 cry for help sways jury.” The article reported on the end of a murder trial in which Sandra Layne, a 75-year-old West Bloomfield woman, shot to death her 17-year-old grandson. Jonathan Hoffman’s parents had moved to Arizona, where their daughter was undergoing multiple surgeries for a brain tumor. Their son had stayed behind in Michigan to finish high school, moving in with his grandparents.

He clearly had problems – but so did his grandmother. “Prosecutors portrayed Layne as a calculating and controlling woman, angry her grandson was failing high school and fed up with his drug use and belligerent attitude,” according to the Free Press account. On May 18 of last year, she killed him, shooting him six times. The key piece of evidence was a six-minute 911 call he made after the first few shots. “I am going to die,” he told the dispatcher. “Help.” On the tape you can hear the gun go off again; the Free Press reported that the bullet hit him in the stomach. Layne was convicted on Tuesday of second-degree murder.

Here is today’s Gun Report.
