Authorities are close to making arrests. It appears that the ducks were indeed run over by a snowmobile:
The break in the Fond du Lac case came when a man in his 30s from the Fond du Lac area called the DNR Wednesday evening, said George Protogere, a DNR warden supervisor.
The man was interviewed by the DNR, but Protogere said he could not discuss the interview in detail because the case is still being investigated.
Tracks in the snow where the ducks were found suggest that the snowmobiler who struck them skipped over open water, turned around and skipped over the water again, Protogere said.
Officials are hoping to speak with a second person who may have been present when the ducks were killed, Protogere said.
"We don't know that person's involvement," Protogere said. "We have to talk to that person to confirm the story. He could have just been an innocent partner who did nothing, but we don't know."
The man who contacted the DNR has not been arrested, Protogere said.
After interviewing the second person, investigators will meet with the Fond du Lac County district attorney's office to determine the next step in the case, he said.
"As the light grows dimmer and the trail begins to fade, my sweetest dreams are those of yesteryear, at deer camp."
