Sheriff Dave Brand said a weekend search for the remains of a 10-year-old boy who went missing in May of 2007 after the boat he was in capsized near the Dresbach dam turned up nothing.
The boy and three family members were thrown into the water when their boat got to close to the dam.
Bodies of the other three were recovered soon after the incident but the boy was never found.
Several boats with search dogs were brought in on Saturday but were unsuccessful.....
Brand also said he is till waiting to hear from the state crime lab regarding a human jawbone that was discovered on an island near Winona's East End Boat Harbor in July.
Brand said earlier authorities do not believe the jawbone is related to the missing boy.....
