Police made a gruesome discovery in a home in San Francisco after a man was reported missing. 

Officers discovered remains of a headless corpse inside a fish tank.

Neighbors say they haven’t seen the homeowner in months. Police were called to the home on Clara Street in the South of Market area to do a wellness check in July.

Officers were reportedly told by several men inside that the homeowner was on vacation 

Police then came back a week and a half ago and made the discovery. The remains so badly decomposed they don’t even know the gender. 

A man has been arrested in connection with the case but no charges have been filed.
