Thomas Holland, 29, was shot to death at his Seguin, Texas, home on December 21, 2017. Officers responding to a 911 call about 8:30 p.m. found Thomas and his wife, 27-year-old Jenita Holland, both dead at the scene.

Authorities arrested a neighbor, Brian E. Day, then 40, and charged him with capital murder. Prosecutors had not disclosed a motive at the time, and investigators recovered suspected homemade explosive devices and firearms at Day’s residence, prompting involvement from the FBI and the ATF and heightened safety measures in the neighborhood.

The couple’s deaths devastated family and neighbors who remembered them as loving and kind. Anyone with information about Thomas, Jenita, or the events of December 21, 2017, is asked to come forward.
