In the late summer of 2021, three people were found shot to death inside an apartment on Walnut Street in Lebanon, Indiana. On September 8, 2021, 20-year-old Brannon Orione Martin was discovered dead along with his 42-year-old father, Larry A. Beeker Stogsdill Jr., and 19-year-old Grace Bishop. Police responded after a report that three individuals might be dead inside the residence; all three victims had gunshot wounds to the head.

Relatives suggested the killings might have been drug-related, and neighbors had previously complained about loitering and suspected drug activity at the building. Investigators developed a suspect, 42-year-old Chad Grimball of Thorntown. Authorities reported cigarette butts at the scene with Grimball’s DNA, cellphone records placing him and another person near the apartment, and surveillance footage showing shoes with a tread matching prints found at the scene.

At trial in August 2023, a jury found Grimball guilty on three counts of murder; prosecutors also cited a jailhouse conversation Grimball had shortly before the slayings as part of the evidence. Does anyone have information about Brannon’s life in Lebanon or about activity around Walnut Street in 2021?
