John Arnold McDowell, 49, was shot dead in Marble Falls, Texas, on September 13, 2022. Police were called about a domestic disturbance at a Cedar Drive residence around 1:50 a.m.; officers found John McDowell in the side yard with fatal gunshot wounds and his sister, 52-year-old Teresa Gail McDowell, in the driveway, also fatally shot.

The suspect was identified as 52-year-old William Allen Rutland, described as having a dating history with Teresa McDowell.
