Ex-boyfriend of missing Minnesota mom arrested for murder as human remains found.

Madeline Kingsbury's ex-boyfriend and father of her children, Adam Fravel, has been arrested on suspicion of murder after human remains were found off Highway 43 in Minnesota. Kingsbury, a mother of two, disappeared on March 31 after dropping off her children at daycare with Fravel. Fravel was the last person to see her alive and had insisted he had nothing to do with her disappearance. The family is in the middle of a custody battle over the children with Fravel, who petitioned for custody after their mother vanished.
