MSP seeking tips in finding missing Kent Co. girls Authorities are seeking the public’s assistance in locating two girls who may be endangered. Authorities say 12-year-old Alexis Ypma and 9-year-old Jenna Ypma may be with their father, Joel Ypma, in northern Michigan. He was supposed to take the girls to school in Byron Center Monday, but failed to do so and isn’t being cooperative with turning his children over. Authorities said family members are concerned about his mental state and that he is suffering from paranoia and believes he is being followed. Joel Ypma is driving a black 2014 Jeep Grand Cherokee with a Michigan license plate No. BMK 5222. He was last believed to be in the Mackinac City area.
