Substance Found at Tulsa Jail Tests Negative for Bio Chemicals

Posted: Updated:

Tulsa jail mail room workers discovered an unknown powdery substance in an envelope addressed to an inmate, Wednesday, June 26.

According to Major Shannon Clark with the Tulsa jail, around noon workers discovered an envelope within an envelope. Inside the second envelope was a note, written in English and an unknown white, powdery substance.

"The investigators at the jail initially conducted a field tests thinking it was a narcotic, because routinely people try to smuggle in drugs, narcotics and other types of contraband through the U.S. Mail," said Clark.

The test came back inconclusive, so the Tulsa Fire Department's Haz-Mat unit was contacted to assist in the investigation. Further tests did not lead to a definitive conclusion, so the substance has been transported down the turnpike to be tested in Oklahoma City lab.

The Tulsa County Sheriff's Office received information around 9:30 p.m. stating that the substance tested negative for any biological chemicals. However, additional tests will be run to determine what the substance is. The tests could take up to five days, according to TCSO.

"We know that sometimes those envelopes are laced with any type of narcotics or drugs and things that are routinely tried to be smuggled into jails," said Clark. "[Staff members] notified their supervisor, they started to alert the investigators of what had actually transpired, so we narrowed it down to the limited staffing members that had to have any exposure to it and then we contacted the professionals to do what they do best."

Staff members have been isolated and are under the direction of the Tulsa Haz-mat unit. They will go through a decontamination process, along with the area where the chemical was found.
