MARQUETTE - Michigan State Police at the Negaunee post said Tuesday a recent pathologist report on the cause and manner of death for a woman whose badly decomposed body was found last month in Wetmore Pond was inconclusive.
Sgt. Kevin Dowling said that because of the advanced decomposition of the body of Amy Luella Janson, 25, of Marquette, the pathologist ruled the cause and manner of death as unknown.
Janson's body was discovered by hikers Sept. 13. Police said she was considered missing in May after some of her personal belongings, including a backpack, were found in the woods near Wetmore Pond, a bog located off Marquette County Road 550, about seven miles north of downtown Marquette.
Dowling said based on the state police missing person's investigation, the evidence at the scene and the pathologist's report, no circumstances emerged to suggest Janson met with anything suspicious.
"We have no reason to believe she was a victim of foul play," Dowling said. "The pathologist investigation didn't uncover any evidence of foul play."
Dowling said one of the things pathologists look for in such examinations is evidence of blunt trauma to the body. None was discovered.
Because of the advanced decomposition of the body, determinations of whether drugs, alcohol or drowning were involved were not possible to make, Dowling said.
Police said previously Janson did not have close regular contact with anyone, and consequently she was not reported as missing to the police and some people assumed she had just left the area.
After the belongings were found, police conducted a search, using a canine unit and divers, centered on Wetmore Pond.
Due to the depth of the silt in the pond and the lack of visibility, though, divers were not able to effectively search and clear the area.
