One man died and another was injured after they apparently fell through some ice and went into a northern New Jersey lake on Sunday afternoon.

The men became submerged in Indian Lake in Denville at about 2:45 p.m. Sunday, said Capt. Jeffrey Paul, a spokesman for the Morris County Prosecutor's Office.

Emergency responders soon arrived and quickly pulled out one man, identified only as a 37-year-old Morris Township resident. But Steve Savare, a 36-year-old Denville resident, was harder to reach and remained in the chilly waters for about 30 minutes.

Savare was taken Morristown Memorial Hospital, where he was pronounced dead at about 6:15 p.m., Paul said. The other man was taken to a different hospital, and further details on his condition were not disclosed.

Investigators were trying to determine why the men were on the lake and what caused them to fall in the water, Paul said.
