According to court documents, Tressia St. Clair, who was in the hospital during the confrontation, told investigators that Davis lived in a trailer house at 3 Shadow Lake Drive owned by Tressia and Denver St. Clair.
She told investigators that Denver St. Clair thought Davis owed him $7,000 for living in the trailer home.
Brad Davis' brother told investigators that on Dec. 20, Denver St. Clair said “he was going to pull Brad out of that trailer by his throat.”
St. Clair was under a permanent protective order filed in 2008 by his wife, Tressia Ann St. Clair.
She lived in the home where Denver St. Clair was killed.
In the 2008 protective order, Tressia St. Clair claimed she found her husband embraced in a “sexual way,” with a drinking buddy and that he later grabbed her by the neck and threw her through a bathroom door.
A domestic assault and battery misdemeanor case against Denver St. Clair filed in Pottawatomie County District Court that year was dismissed, according to the Oklahoma Supreme Court Network website.
Denver St. Clair filed for divorce on Sept. 30, 2013; this was the third time the couple filed for divorce.
The first two divorce filings were dismissed and were filed in 2004 and 2010 by Tressia St. Clair.
