(KMOV.com) -- A scientist from the Illinois State Police crime lab in Fairview Heights is on administrative leave after a police agency noticed a problem with evidence that was returned to it from the lab.
Lab officials have notified 36 State's Attorneys of potential problems with evidence.
The investigation is just beginning and the lab doesn't know if a pattern will develop or if the one case of mislabeled evidence will be an isolated incidence.
The scientist hasn't been identified.
No criminal activity is suspected.

FAIRVIEW HEIGHTS, Ill. (AP) -- Illinois State Police say they're blocking a southwestern Illinois crime lab's scientist from more casework in drug cases after calling into question some of his work.
State police say the unidentified scientist at the Metro East Forensic Science Laboratory in Fairview Heights is suspected of not following strict internal quality controls in certain drug-chemistry cases.
Those questioned cases are being reviewed by state police forensic investigators to pinpoint the issue's scope. Results will be reported back to the agency that first submitted the case to the lab.
State police are notifying all the prosecutors' offices for which the scientist analyzed evidence.
Officials with the state police haven't returned messages seeking more details Wednesday.
