Authorities say a neighbor -- who smelled a foul odor coming from the Taylorsville duplex unit, adjacent to his -- led them to a deceased man.

Authorities aren't sure how long the man, 61, might have been there, but say it could be days, or even weeks.

The man was found near 45th South, 23rd West.

The neighbor reports not seeing the man for about a year.  But, authorities say it's possible he left for a time and recently returned.
