The human remains found on Sunday were encased in about 500lbs of ice when removed from a pond by the Minnesota River in Burnsville
Dakota County Sheriff Tim Leslie told BMTN that the medical examiner's office is still waiting for the ice to defrost so they can conduct an autopsy.
And because the body is still frozen, police haven't been able to determine whether it is that of a male or female, or the age of the victim.
The body is badly decomposed, some of it "skeletal," Sheriff Leslie said, and because it's been frozen the date of death could have been as early as December or January.
It was found in a holding pond near the river, with police having to cut the ice around the body to remove it and preserve any evidence in the ice surrounding it.
Death is suspicious, sheriff says
What the sheriff's office does believe however is that the death is suspicious.
Without giving any details as to how it knows this, Sheriff Leslie says investigators do not believe the victim drowned.
The remains were found near an underpass beneath I-35W at Black Dog Road in Burnsville on Sunday.
Sheriff Leslie says that missing persons reports are forming a part of their investigation.
It's hoped that the body will have defrosted enough so that an autopsy can be carried out on Thursday, with more details expected to be released after.
