On November 12, 2023, 42-year-old Geoffrey Shane Buckley was shot and killed in the parking lot of Lake Houston Methodist Church in Huffman, Texas. According to reports, Buckley approached a church member earlier and said Today is going to be the day, referencing the pastor, which prompted members to call authorities. Deputies were en route when Buckley fled; a church member who is a Texas EquuSearch volunteer went to the parking lot and, after Buckley allegedly charged at him, fired two shots that fatally wounded Buckley. About 50 to 70 congregants were present; no one else was reported injured.

Investigators noted Buckley had been arrested the day before on a criminal mischief allegation involving a sword and a trailer, and psychotropic medications were found in his vehicle at the scene. Buckley was born January 22, 1981, in Houston, served in the Navy and the Army, worked as a Texas State Inspector for Copperfield Goodyear from 2020 to 2023, and is survived by his wife Vanessa, his parents, and siblings. A service with military honors took place December 11, 2023, at Houston National Cemetery.

Did anyone who attended the service or was at the church that day notice interactions with Buckley in the hours before the shooting?
