On Sept. 8, 2021, an acquaintance found the bodies of 20-year-old Grace Bishop, 21-year-old Brannon Martin and 42-year-old Larry Stogsdill Jr. in an apartment in Lebanon, as Front Page Detectives previously reported.
Autopsies revealed each victim died from a single gunshot wound to the head.
Investigators used DNA on cigarette butts collected from an ashtray in the apartment to match it to 42-year-old Chad Grumball, officials said.
Authorities also used cell phone records for Grimball and another person, who allegedly drove him to the crime scene. The records show their cell phones appeared to enter and exit the apartment complex at the time the shootings took place.
On the morning of the shooting, Grimball reported to the Boone County Probation Department. Video from the Probation Department showed him wearing shoes with a tread pattern that is consistent with those left at the crime scene, court documents state.

In August 2023, a jury found Grimball guilty on three counts of murder and a charge of carrying a handgun without a license, officials said.
In a statement, Prosecutor Kent Eastwood said, "Today’s sentence means that the Defendant will never walk free again. He will spend the rest of his life in prison for the heinous and cowardly acts he committed that day.”
