Officers convinced Wilson to free the woman and were led on a high-speed chase along the Interstate 35 river bridge south of the Interstate 40 eastbound junction.
Wilson appeared to lose control of his vehicle before it came to a stop. Officers found Wilson dead inside the car of a self-inflicted gunshot wound.
Four children were in the home, ages 9, 5, 2 and 1. They were taken into protective custody.
The woman with Schnittman who was taken hostage told police she'd been sexually assaulted. The Oklahoman's policy is not to name victims of sexual assault.
Schnittman had filed a protective order against Wilson on Dec. 4, court records show. The protective order was denied.
Darrell Wilson was distressed about being apart from his children and because of his estrangement from their mother, said his brother, Kevin Wilson, on Saturday.
Darrell Wilson had worked at Tinker Air Force Base for a defense logistics company. He'd recently taken some time off to take care of his emotional health, his brother said.
“My family is devastated that Schnittman's life was taken,” Kevin Wilson said. “He's definitely a victim in this situation and we feel horrible about this.”
Kevin Wilson described his brother as a family man who would do anything for his children. The estrangement from his wife and children had taken a toll on his mental health. Darrell Wilson was worried the children were in danger with their mother, Kevin Wilson said.
Darrell Wilson posted on his Facebook page and sent messages to his family describing his depression and frustration before friends and family learned he'd killed himself and Schnittman early Friday morning.
“He left a note at the home saying he was sorry he ruined Christmas and had left food and water for the dog,” Kevin Wilson said.
Darrell Wilson had filed for divorce from his estranged wife Monday, court records show. He also filed a victim's protective order against his estranged wife, but that was denied.
A decision had not yet been made on a protective order Darrell Wilson's wife filed against him.
