(Corning) -- More information has been released on the weekend drowning incident in Adams County.

The Powers Funeral Home in Creston lists the victims as 11-year-old T.J. Frey and 9-year-old Nathan Frey, both of Creston. The sons of Tom and Leisa Frey were students at St. Malachy School in Creston. Adams County Sheriff Alan Johannes and Corning Fire Chief Donnie Willet held a press conference at the Corning Fire Station late Monday morning to release further details on the incident which led to the boys' drowning in a farm pond at 1623 Vanilla Avenue in Prescott. Willet says local authorities were called to the pond at 5:34 p.m. Saturday after the boys fell through the ice. Agencies responding included fire and rescue units from Prescott, Creston and Corning, ambulances from Creston and Adams County, the Iowa State Patrol, Clarinda's Mercy One and the Des Moines Mercy Three Helicopters, and the Des Moines Lifeflight unit, and members of the Midwest Regional Dive Team, comprised of divers from several area communities.

"Thank goodness the Creston Fire Department had two ice suits, that they went into the water," said Willet. "They found one of the young children in the water, about a foot under the water, very shortly. It took about 20 minutes to find the other child."

EMTs administered CPR at the scene. The medical helicopters transported the two boys to a Des Moines hospital. Johannes and Willet say 911 was called after the boys failed to return from playing outside. A hole was discovered in the center of the ice, with clothing floating on top.

"Sounded like the kids were just out playing," said Johannes. "Nobody has an idea what they were doing out on the ice. They were just farm kids outside playing."

"It was a nice day," said Willet. "It was a beautiful day out. They were out exploring."

Willet says the ice in the pond wasn't very thick.

"The ice at the edge of the pond was approximately 2 1/2 to 3 inches thick," he said. "Out where the kids fell in, the divers were breaking the ice with their fists. It was a lot different from shore to the center."

Johannes says the incident demonstrates how individuals should check the thickness of the ice before ice fishing. He says the boys' family has asked the media to respect their privacy. Condolences and memories of the two victims can be left at the Powers Funeral Home's website.
