On the evening of March 24, 2020, 25-year-old Brendan Anton van Zweel of Fairland, Oklahoma, went with his mother and her brother to the rural trailer home of the mother’s former boyfriend at Gray’s Ranch along 60800 East 230 Road after learning the man was threatening self-harm. According to investigative and news accounts, the 48-year-old man, Edwin Ball, opened fire as the three reached the door, striking and mortally wounding Brendan. The mother’s brother, described as Brendan’s uncle, was also shot and survived after being taken to a hospital in Joplin, Missouri.

Ball reportedly retreated into the trailer and fired repeatedly at deputies and Oklahoma Highway Patrol troopers who established a perimeter. A trooper, identified as Trooper Jeff Laue, was struck in the eye by a pellet or shrapnel and required hospital treatment. Negotiators and a tactical team spent hours at the scene; gas was eventually used to force Ball out and he was taken into custody shortly after 5 a.m. Investigators opened a homicide case and Ball was booked as the sole suspect in Brendan’s death.
