Emergency responders from Dallas have given the all clear at a hazmat investigation in DeSoto near U.S. 67 and Wheatland Road in southern Dallas County.
DeSoto Fire Marshal Michael Laws said a doctor opened a letter and white powder fell out. It happened Monday at 2727 Bolton Boone Drive.
“One of the doctors here opened a letter that contained some powder. He immediately put the letter down and called 911," said Laws.
The DeSoto Fire Department and a Dallas hazmat team went to the Southwest Professional Plaza, a medical office park adjacent to the Methodist Charlton Medical Center on Wheatland Road.
According to Dallas Fire-Rescue, only people who were near the package were evacuated and there were no reports of injuries.
The white powder was tested by Dallas Fire-Rescue's hazmat crews and determined not to be hazardous.
If the package is determined to be connected to other recent incidents regarding white powder, the case will be referred to the FBI.
Investigators would not say where the letter was postmarked, or to whom it was addressed.
So far, all of the letters that have popped up across the nation have tested negative for hazardous material, Laws said if another letter pops up, investigators treat it as a potentially dangerous situation.
“We have to treat them, each one, as if it were real because we don’t know. Somebody could be setting someone up for later. Wait till people get complacent and then actually put something harmful. We just don’t know,” Laws said.
