MINONG, WI (KBJR) -- A weekend fire claimed the lives of two children in Northeast Wisconsin. Flames broke out around 4:45 Saturday morning at a home on West Semrad Road in Minong. Inside were 10-year-old Phoebe Denhartog and her 13-year-old brother, Thatcher. Neither made it out. Mark Denhartog will always remember his 39th birthday party as the last time he was with his two youngest children. "They said good-bye. I said good-bye. Then I walked out the door. That was the last time I got to see them. I got to say I love you and good-bye," said Denhartog. Denhartog then left to take care of his mother several miles away.
