A missing-person case in Des Moines has sinister overtones. The missing man, 38-year-old Kurt Peterson, left his wife a note on Sunday. He’d been sick the previous week and apparently intended to go in to work a while. Peterson’s older brother, Mark Peterson of Stanton, says the last sign of Kurt was an ATM withdrawal on Sunday after he’d left his home in the Drake neighborhood of Des Moines. The police had to wait 24 hours after his departure, but now have listed the Peterson as missing. Mark Peterson is at a loss today. He says can’t imagine Kurt doing this. Police reportedly are considering the possibility that the man was accosted by someone who saw him make a cash withdrawal from an ATM. That bank-machine transaction is the last sign of Kurt Peterson, whose brother says he would never have simply left his wife and two preteen daughters.
