Cullen Davis, an American oil tycoon and murder suspect, died November 6, 2026, aged 93. Born Thomas Cullen Davis in Fort Worth on September 22, 1933, he was the son of oilman Kenneth W.
“Stinky” Davis and attended Arlington Heights High School. His father founded KenDavis Industries International, which manufactured products for the petroleum industry. When Kenneth Davis died in 1968, Cullen and his two brothers received equal shares of the estate. Davis became widely known through two high-profile criminal trials in the 1970s. In 1976, during a contentious divorce from his second wife, Priscilla, he was accused of killing his 12-year-old stepdaughter. A jury acquitted him. Two years later, he faced allegations that he had tried to hire a hitman to kill Priscilla and the judge overseeing the divorce; he was acquitted in that case as well. At the time of the first trial, Davis was believed to be the wealthiest man in the United States to stand trial for murder. The trials brought national attention to the oil heir and the allegations against him, though both cases ended in acquittals.
