Betty Johnson, 76, and her 72-year-old husband James Johnson were found dead from gunshot wounds at their rural home near Saint Joseph, Missouri, in Buchanan County on the early morning of July 4, 2015. Deputies arrived about 1:00 a.m. during the holiday weekend and discovered both victims inside the family residence. There were no signs of forced entry at the home, which led investigators to focus on people who lived there.

Law enforcement quickly took the couple’s 16-year-old grandson, Joseph Johnson, into custody. Authorities allege the teenager armed himself with two 9mm pistols belonging to his grandfather, concealed them, then entered the living room where his grandparents were seated and shot them. Prosecutors charged him with two counts of second-degree murder and the case began in juvenile court.

The case record mentions claims by the teen that a strict, isolating home environment contributed to his actions. Did anyone in the Saint Joseph area know the Johnson family or have information about the household leading up to July 4, 2015?
