The Missouri Department of Conservation says thieves have stolen catalytic converters from some of its southwest Missouri river access sites recently.

The Department reports that thieves have targeted unattended vehicles parked on river accesses in Pulaski and Laclede Counties in an effort to steal catalytic converters.

Officials say that law enforcement has followed up on eleven reports of catalytic converter thefts from accesses in both counties since June. The Missouri Department of Conservation is asking visitors to use caution when leaving cars unattended.
