It's come to this

A woman and her daughter were charged with incest after getting married in Oklahoma this year, authorities said.

Patricia Ann Spann, 43, and her daughter Misty Velvet Dawn Spann, 25, were married in March, police learned last month while conducting a child welfare investigation. Authorities later found out Patricia Spann had married her son in 2008, who filed for annulment 15 months later citing “incest.”

The motivation behind the marriages is unclear.
