Officials might never be able to identify the substance that sickened four confinement officers at the Allen County Jail Tuesday.
Two officers searched a cell in the women's section of the jail around 5 p.m. and found a towel draped over a toilet. Smoke emerged from the toilet when the towel was removed, and officers began feeling dizzy, lightheaded and ill soon afterward.
Two other officers reported feeling ill after they went into the cell.
Steve Stone, a spokesman for the Allen County Sheriff's Department, said Wednesday no residue was left from the substance, making it difficult to determine what the officers were exposed to.
"There's nothing to test," he said.
It was the second time since November a drug found at the jail has caused a lockdown at the facility. In November, a substance was found on a piece of paper, and dozens of officers were treated for symptoms.
Stone said the substance present Tuesday did not appear to be the same as the one discovered in November.
