An Illinois couple and their two children have been missing for over two months, with the husband having been previously ordered to stay away from the family home over a domestic violence incident. The family's phones last pinged in Richmond, Indiana, and a warrant has been issued for the husband's arrest. While there is no evidence to suggest the family is in immediate danger, authorities are taking necessary precautions due to the length of time they have been missing.
