He described a strange sensation similar to smelling ammonia.
"Myself and the chief's secretary just felt light headed and you know like something that you know hits you right in the face," said Captain Warych.
Both were given the overdose drug Narcan as a precaution and were sent to the hospital.
"There was no powder there was nothing in there it just a blank piece of paper," explained Warych.
There was a similar scene at the Oak Creek Police Department the very next day back in August. A Lieutenant told TODAY'S TMJ4 they knew not to open the letter they received, thanks to the warning by Green Bay Police.
"Ours was not opened we received an email from Green Bay and our clerical staff noticed it had a similar envelope packaged envelope that was similar to Green Bay," said Lt. David Ashenhurst of Oak Creek Police in August of last year.
Captain Warych tells us he felt better about 45 minutes after the incident and was back to work the same day.
"So at this point it's unknown why we felt the way we did and going forward you know we just have to be more cautious about opening up packages," said Captain Warych.
The FBI sent us updated information Tuesday morning about whether they tracked down who sent these packages. Spokesman Leonard Peace tells us a person was interviewed in Green Bay. Agents learned the person was the victim of a scam and did not know what he was sending. Peace tells us because no hazardous materials were found in Oak Creek, they did not investigate this separate case any further.
