An Oklahoma Department of Human Services child welfare investigator discovered information that led her to believe that Misty and Patricia Spann's relationship was incestuous, according to Tulsa World.
The two women reconnected back in 2014, reportedly "hit it off," and chose to get married.
Patricia said she didn't think she was breaking any laws by marrying Misty because her name is no longer listed on her daughter's birth certificate, according to officials.
Investigators told News 4 that 43-year-old Patricia Spann lost custody of Misty, 26, and two other children when they were young.
The 44-year-old also got married to her son in 2008 in Comanche County, however he filed for an annulment after 15 months.More news: Moscow plans retaliation to "US pressure on Russian media"
