The Goodhue County Sheriff Department still has this an an open/unsolved case. I was allowed to view their case file.
The file indicates that although the autopsy did not find any indication of foul play, the description of the burial indicates that it was done in a hurried and unconventional manner.
The body was buried only one or two feet below the surface, and in a "crouched or fetal" position.
The autopsy report indicates that he had suffered a broken nose at some time, as well as a broken (and well healed) fracture of the left femur (upper leg bone). This injury would likely have caused the man to walk with a limp.
Dentition was poor. Many teeth were missing, and those found with the skull were worn down. None had fillings. Some teeth had been missing for a long time, as evidenced by the sockets of the jaw bones filling in. A few teeth were more recently missing. An abscess cavity was noted where teeth were missing. Sepsis from this, it was speculated, could have contributed to the man's death, but there was no way to determine that positively.
Most of the skeleton was present for examination. From a number of measurements, it was determined that the man was about 5 feet three inches tall, and was between 60 and 70 years of age.
The condition of the bones indicated that they had been in the ground for "a moderately long length of time". "This would be on the order of from 20 to 100 years, but probably within the middle range of this estimate, probably 50 to 60 years buried would be a good estimated time".
This estimate would place the burial date some where between 1924 and 1934.
There was no indication in the file that any clothing or personal items were recovered from the burial site.
