The mother of two missing boys has issued an emotional plea for their safe return after they were allegedly kidnapped by their father five weeks ago, saying she will 'never stop looking' for them. Sandra Hughes Dohm reported her sons Parker, eight, and  Jaxon, seven, missing on February 9 after her former husband, Kristopher Dohm, 36, reportedly failed to return them to her New Jersey home. The boys had been scheduled to stay with their father for a week. Under a custody agreement that was made during the couple's 2012 divorce, Dohm was required to bring them home after the trip. But instead, he abducted Parker, who has asthma, and Jaxon and drove out of the state in his 2009 grey Nissan Pathfinder to an unknown destination, police said. The boys have not been seen since.
