The survivors of the crash were taken to South Bend Memorial Hospital. Spokeswoman Maggie Scroope said Monday that Jim Rodgers was in serious condition and Christopher Evans was in fair condition. Davis' parents said they didn't know the relationship between their son and Rodgers and Evans.
A woman who neighbors said lived in the middle house that was struck, Diana McKeown, was in fair condition, Scroope said. Edgar Diaz, a spokesman for the hospital, said the survivors have declined requests for media interviews.
Caves' plane took off from Tulsa and is registered to 7700 Enterprises in Helena, Mont., which does business in Tulsa as DigiCut Systems and is owned by Caves. DigiCut Systems is in the automotive coating business.
In 2009, the company was named as a defendant in a federal lawsuit brought by a former female employee hired to be Caves' executive assistant. She claimed sex discrimination, retaliation and wrongful discharge. Federal court records indicate the suit was settled in 2011 without going to trial.
During his football career, Steve Davis went 32-1-1 as the Sooners' starter from 1973 to 1975, starting every game of Barry Switzer's first three seasons as head coach. They won two national titles in Davis' final years at the school.
Davis had joined the Tulsa church, which has about 3,600 members, a couple of decades ago, but his travels and work took him elsewhere, Spoo said. He noted that in the last few years, Davis had become a more active member of the church.
"As followers of Jesus, we have two commands: One is to love God; the other is to love people, and Steve fulfilled those commands with excellence," he said.
Patsy Davis said her son was a loving and caring family man.
"He always hugged me and said, 'I love you, Mom,'" she said. "He always called, but he was pretty busy so he didn't come to Sallisaw very often."
