When you consider a single ecstasy pill costs 20 dollars, the potential impact of this seizure could run into the tens of millions of dollars.
Day after day on Pattiglen Street, children walked unknowingly past a source of deadly poison.
A covert manufacturing plant churning out millions of dollars worth of dangerous drugs.
"I would say we stumbled across this, this is nothing that we were prepared to encounter when we came to this residence," says Greg Palmore with the Department of Homeland Security.
Federal agents came to this two story rental looking to making an arrest.
When a suspect jumped out a second story window just prior to being captured, officers entered the home and were staggered by what they found.

"It's estimated that this guy has probably been putting out hundreds of thousands of ecstasy tablets throughout the Houston area for the last year. This is the first time that we've uncovered an ecstasy manufacturing operation here in Houston," Palmore says.

Neighbors called the 30-year old suspect quiet, but a subject of curiosity because of his string of expensive vehicles.
"He's had Chargers, Challengers. I always though he worked for a Dodge dealership," says neighbor Tyrone Taylor.
Agents say the inside of the structure is a virtual hazmat site, with a thick layer of powder residue cloaking walls, flooring and furniture.

"And it's sad, its sad to see the things they're taking out of there and how much drugs were actually coming out of that house and none of us were aware, " says neighbor Glena Ferguson.
No idea if this house can even be decontaminated or when.
A new detail tonight, a neighbor tells us she saw young children going in and out of the house. A truly disturbing detail.
