The debris of a Detroit house owned by state Rep. Sherry Gay-Dagnogo that was mysteriously demolished has been found at a landfill 21 miles away in western Wayne County, the Free Press has learned.

The Woodland Meadows landfill, owned by Waste Management, has informed the Detroit Police Department the debris was disposed at their facility located in Wayne, Michigan, in Van Buren Township.

The discovery is a major development in a story that made national headlines earlier this week.

"I have received some information that the demolition project was disposed of at our Woodland Meadows site," Waste Management spokeswoman Tanisha Sanders confirmed Friday morning. "Our site has obviously been cooperating with the local police department so we've shared that information with them already."

Sanders said Waste Management is not certain of who was actually responsible for the demolition but they do know who hauled the materials to the landfill. Sanders declined to share the name of the company. Gay-Dagnogo's home is on the west side of Detroit.

"It doesn't necessarily mean that the person who hauled it demolished it," Sanders said.

When reached for comment, Gay-Dagnogo said she is pleased that the Detroit Police Department and the general public have "demonstrated a commitment to finding out who has demolished our home."

"This has been an enormous learning experience and I am eager to learn who our home was demolished by and why."

Gay-Dagnogo told the Free Press last week that the demolition of the west-side house near the Brightmoor neighborhood should have never happened and likened it to a modern day whodunit.

"I have a lot of questions," Gay-Dagnogo said at the time, adding that she didn't live in the home but was in the process of renovating it. "There's no record at all at the city, from what they can find so far, that has anything about my house being torn down. They have no idea. It's a mystery. I'm just taken aback and trying to process this. How could this happen?"

The Free Press independently reviewed the city's data portal website and found no record of a planned or completed demolition of Gay-Dagnogo's property, at 14567 Minock St.

The Free Press' review also found no demolition permits pulled for the job.

Detroit Building Authority Director Tyrone Clifton said in an earlier statement that the demolition "was not ordered, directed or funded by the city."

"There also was no permit pulled by any private party for demolition at this address," Clifton said. "At this time, we are actively investigating to see if we can help determine who was responsible."

Gay-Dagnogo addressed the Detroit City Council earlier this week and announced a $1,000 reward for information.
