An Arkansas father who discovered his missing 14-year-old daughter in the clutches of a 67-year-old sex offender who had been stalking her for months has been arrested on charges of murder.

Aaron Spencer, 36, reported his daughter missing on Tuesday, and Lonoke County Sheriff’s Office deputies were dispatched to his home.

But as deputies were en route to the residence, they learned that Spencer had found his daughter in a vehicle with Michael Fosler, 67, who had a “no contact order” with the girl for stalking and raping her.

A confrontation ensued between the two men before Spencer allegedly shot and killed Fosler.

Fox report: Deputies arrested Spencer on a preliminary charge of first-degree murder, a Class Y felony. He was booked into the Lonoke County Detention Center before being released the next day after posting bail.

Spencer’s wife, Heather, said on Facebook that the couple called 911.

“We absolutely called 911 during the entire event,” she wrote. “We had no idea this man was in contact with our child again. He was waiting 6-9 felonies for what he did, not 2. He was looking at the rest of his pathetic life in jail, and our daughter was the only witness.”

“Some things we will never know, but we know that the police department afforded this predator privacy they did not give our family,” she continued. “Including posting our home address. I’m deeply offended by the way this was handled by the county [sheriff’s] office.”

The woman added: “At the end of the day, our daughter is a victim and we have a long road of recovery for everyone. We are so thankful for all the calls, messages and prayers.”

Fosler had been arrested by another law enforcement agency in July and booked for internet stalking of a child and sexual assault, Staley told USA TODAY.

“I absolutely do not support predators,” he said. I’m a daddy. “I have three daughters. I know she’s hurt right now, but there’s absolutely nobody I would put ahead of our children, their children, my children.”

The sheriff said deputies are looking into what happened leading up to the shooting.

Sheriff John Staley said in a video on Facebook that Spencer has not been formally charged yet and that the District Attorney’s Office will decide which charges to file.

“This is a tragic situation and my thoughts and prayers are with all involved,” Staley said.
