An Oklahoma mother who married her daughter after the two "hit it off" was sentenced Tuesday to two years in prison after pleading guilty to incest.

Patricia Ann Spann, 45, of Norman, Okla., pleaded guilty to the felony offense and admitted she married her biological daughter, 26-year-old Misty Velvet Dawn Spann. She must also register as a sex offender after her release from prison, the Oklahoman reported.

Spann accepted a plea deal and was also sentenced to eight years on probation and fined $1,500.

The Duncan Police Department was informed of the incestuous marriage by an employee with the state's Department of Human Services. The employee found out about the marriage during a "child welfare investigation," police said.

The mother and daughter wed in March 2016 after they reunited in 2014. Patricia had lost custody of Misty years before but the two "hit it off" after reuniting.

Detectives later learned she married her son in 2008. He filed for an annulment 15 months later citing "incest," stating he was married to his birth mother, according to the affidavit.
