Details of Disappearance
Kenneth and his brothers, Daniel and David, disappeared together from Minneapolis, Minnesota on November 10, 1951. The boys left their home in the 2900 block of Colfax Avenue north at 1:30 p.m. to go to Fairview Park at Lyndale and 29th Street, four blocks away. They were never heard from again.
Investigators believe it's likely the Klein brothers drowned in the Mississippi River. The river runs near Fairview Park, and a tracking dog traced their scent to the riverbank, where it lost the trail.
Searchers found two of the children's caps in the river near the dam, and two Roman Catholic catechisms belonging to the boys were found on a brush pile near the riverbank. However, an extensive search of the river turned up no other sign of them or their remains.
The search was called off on November 16, and none of the brothers were ever found. The Klein children's parents continued to hope they were alive, and up until the 1990s they advertised in the newspaper asking for any information leading to their whereabouts.
Daniel, David and Kenneth left behind one older brother, and their parents had four more sons in the years after they disappeared. Their cases remain unsolved.
