MONTEZUMA, Iowa (AP) — A search is continuing for the body of a man who fell into Lake Ponderosa when ice broke beneath the all-terrain vehicle he was riding. KCCI-TV reports that authorities identified the man as 57-year-old David Hartke, of Grundy Center. Montezuma Fire Department Chief Chris Widmer says the effort is now considered a recovery mission.

Hartke fell through the ice Saturday evening after ice fishing at the lake near Montezuma, about 50 miles east of Des Moines. The initial search for the man continued until about 2 a.m. Sunday when it was called off because equipment kept freezing. The search continued Sunday afternoon. Widmer says divers were plunging into 37-degree water as the searched for the body.

Members of the Midwest Regional Dive Team, including persons from southwest Iowa, began their search efforts for Widmer at Noon, Monday.
