LAFAYETTE. Ind. (WLFI) — A pacemaker is being used to tie a Lafayette woman to her brother's murder. 25-year-old Tianna Holmes is accused of stabbing her brother to death in the apartment she shared with him on November ninth.
Holmes told police they'd spent the day drinking and she left for about an hour after other people came over and they argued. She told investigators that her brother, Deron Keaton, was stabbed while she was out of the apartment. She called 911 and said he was still alive at that time.
Keaton had a pacemaker and its manufacturer was able to pinpoint his time of death at 1:45 a.m., a time when Holmes was the only one with him. Prosecutors said he died within minutes of being stabbed and Holmes was the only one who had the "time and opportunity" to have stabbed him.
Holmes was charged with a single count of murder Tuesday.
