(MSC News)--Life in prison for a Saint Joseph teenager.
That's the sentence handed down for 17-year-old Joseph Johnson, accused of killing his grandparents last summer.
KQ2-TV reports Johnson learned his fate Wednesday in a Buchanan County courtroom.
In December, Johnson, calling himself “spoiled and stupid,” entered a guilty plea on two counts of second degree murder.
Johnson was 16-years-old at the time of the killing, and was tried as an adult.
Authorities say 72-year-old James Johnson and 76-year-old Beverly Johnson were shot in the head on July 4th, 2015, at the home they shared with their grandson, just east of Saint Joseph.
It's believed James Johnson was also strangled.
The teen was arrested during a traffic stop in Platte County hours after the bodies were discovered.
