The St. Louis County search and rescue squad has been called to assist in one of the most talked about cases in the country today.
23–year–old Stacy Peterson of Illinois has been missing for over two weeks.

The Illinois State Patrol contacted the St. Louis County Rescue Squad due to its expertise and advanced equipment.

"We've been very successful in search efforts here in St. Louis County and in Northeastern MN and I think the authorities in Illinois are aware of our track record," said St. Louis County Sheriff Ross Litman.

Stacy Peterson's sister has said she believes Stacy was stalked by her husband Drew Peterson who is a sergeant in the Bolingbrook, Illinois police department.

Stacy was last seen on October 28th.

Her car was found near a pond in Bollingbrook. Authorities believe her body may be in that pond.

Suspicion was cast on Drew Peterson who was in the process of a divorce from Stacy.

Drew has been married three times. One of his former wives was found dead in a bathtub in 2004.

That death was initially ruled accidental but Stacy's disappearance has re–opened the case.

Saint Louis County's expertise is in underwater searches.

The squad has both a remotely operated underwater vehicle and a sonar scanner and has become proficient in dangerous underwater searches.

"Any time you put a dive team under water or ice you are taking a risk. Diving is dangerous," said St. Louis County Sheriff Ross Litman.

The squad plans to stay in Illinois for the remainder of the week.

In the wake of Stacy's disappearance, Peterson's first wife's body was exhumed today for further investigation.
