According to Winona County Sheriff Dave Brand, Hamline University has confirmed that the jaw bone found on a Mississippi River island near Winona, is in fact, human. Experts confirmed the jaw bone belonged to an adult, although the sex of the person has not been identified. Investigators have yet to determine how old the bone is.
The bone does not belong to 2005 missing person Marvin Duane Witt, nor does it belong to 2007 child drowning victim Joshua Xiong.
Brand indicated that a canine cadaver search team from Minneapolis will be searching the Lock and Dam 7 area on September 14 for the remains of 10-year-old Joshua Xiong. The teamís dogs will also search for other remains that may be associated with the jaw bone found on July 26.
