A 15-year-old boy has pleaded guilty to the murder of a popular retired teacher in Hawkins County.
Margaret Jack Sliger, 79, was shot to death in her yard in May of 2015. Last August, authorities announced they had arrested a teenager in her death.
On Wednesday, Kyle Robert Wolfe pleaded guilty to second-degree murder and was sentenced to 25 years in prison.
The district attorney told WCYB that Wolfe lived on a neighboring farm, and it's still not clear why he killed Sliger.
As part of his plea agreement, Armstrong said Strong will have to serve his full sentence behind bars.
