The Chicago Police Department tells Fox News Digital and investigation is underway after human remains were found twice over a period of four days in the same neighborhood. 

The first set of remains was found Wednesday in the 4900 block of West Washington Boulevard in the Austin neighborhood on the city’s west side, according to FOX32 Chicago. 

Trash collectors reportedly made that discovery in an alley. 

A source with knowledge of the investigation told the Chicago Sun-Times that the person had been "dead for a while," and the remains appeared to have been dumped there.
