The Norman Police Department has called off the search for three children who had been missing for four days.
Police said the children were located safely and have been returned to their custodial guardian.
Early Thursday, authorities said 7-year-old Lane Minor, 4-year-old Levi Minor and 1-year-old Lillian Minor were last seen Sunday at a Norman residence with their mother Megan Grigsby, who is 27.
Norman police, however, said the children's grandmother was granted immediate custody.
There are no charges against Grigsby at this time.
