Lake Geneva police are searching for a 40-year-old mother and her three young children after the four disappeared after leaving their home nearly two weeks ago.
Michalene Melges and her three sons -- 14-year-old Hans Melges, 12-year-old Kristian “Max” Melges and 10-year-old Maverick “Buddy” Melges -- were last seen leaving their home in the 900 block of South Lakeshore Drive on May 10.
Michalene Melges rented a van in Lake Bluff, Illinois on May 9 and the van was returned to a rental company in Plano, Texas on May 13, police said.
The family may be traveling with their two dogs, “King, an English black lab, and “Gigi” or “Geneva,” a white Cavalier King Charles Spaniel.
"Everybody we've talked to at this point says this is out of character," Lt. Ed Gritzner told NBC affiliate TMJ4. "Especially since she had called the boys in school excused and then didn't show up when they were supposed to be back."
The boys' parents are reportedly divorced, but police said the disappearance is not believed to be a custody issue, though nothing is being ruled out.
Police said foul play is not suspected.
Anyone with information on the family’s whereabouts is asked to call (262)-248-4455.
