The Chemical Assessment Team was sent to the impound lot at the State Patrol’s headquarters in northwest Rochester “to assist in collecting a sample of an unknown substance which was possibly hazardous.”

RFD says it was told the vehicle had been seized and that “ both vehicles had been contaminated by a possible hazardous material.” The material was collected without incident.

So what was the substance?

State Patrol Sgt. Troy Christianson told KROC News Friday morning, “This is an active investigation and we are not able to comment on this incident.”
