The case of the leg in the lake remains a mystery.
A post-mortem examination has been performed on a human leg found last month in Buena Vista Lake, the coroner's office said Friday, but cause and manner of death remain unknown, as does to whom it belonged.
A forensic pathologist will conduct further studies on the limb.
The leg was found washed up on the shore the morning of July 28. A sheriff's search and rescue team combed the area but failed to turn up other remains.
