Ivy Marie Leinen was 11 when she disappeared from Poplar, Montana, on March 14, 2010. She left her home about 4:00 p.m. to walk four of the family dogs. Within 15 to 20 minutes the dogs returned without her and her family began an immediate search.

Tracking dogs followed Ivy’s footprints to an island in the Missouri River. The footprints and the dogs’ tracks continued onto the ice-covered river and ended at an open hole in the ice. Authorities concluded she may have fallen through the ice and the case is classified as a suspected accidental drowning. Despite extensive searches her body was never recovered.

Ivy was a fifth-grader at Culbertson School and lived with her mother and grandparents; her family held a memorial service soon after she went missing. Does anyone have information about that stretch of the Missouri River or remembered search efforts in March 2010?
