The below article explains it pretty good. I'm still not seeing a mention of the gray bag.

Investigators interviewed the meter reader at length about what he knows, but he is not considered a suspect in any way.
"He is not a suspect in this case," Sheriff'f Captain Angelo Nieves said early Thursday evening. "He is a credible witness and we consider him so at the Orange County Sheriff's Office."
Steve Triggs, Director of Communications for Orange County, said the meter reader had been a county employee for a relatively short time and would appear at a news conference with the Orange County Sheriffs Office Friday afternoon. Triggs said he is being represented by outside counsel at the Countys expense.
The sheriff's office said the meter reader had called in tips about the exact same area to Crimeline and the sheriff's office three times in August, two weeks before Tropical Storm Fay hit and flooded much of Central Florida, including the area where the remains were found last week.
The sheriff's office said it is focusing on its own deputies who came out on August 11 and 13 to inspect the scene. It's unknown what the area looked like on August 11, the first day the meter reader called and reported seeing
a gray bag.
Sheriffs officials said the man called Crimeline on August 12th. A detective checked records and determined the area already had been checked by a cadaver dog.
The sheriff's office is also investigating deputies who came out and cleared the scene on the 13th of August. The meter ready accompanied the deputies but nothing was found.
Officials aren't releasing the names of any of the deputies involved, but they are under administrative investigation.
Nieves said the meter reader went back last week because he had a nagging feeling that it was the place to look.
