A Kentucky mom and her boyfriend were nabbed in Kansas last week more than one year after her 4-year-old daughter Serenity Ann McKinney went missing.

The grandparents of the little girl went to the Shelby County Sheriff's Office, which is located about 30 miles east of Louisville, and reported that the child may be in danger on Jan. 31, Capt. Kyle Tipton told Fox New Digital.
