WAGNER, S.D. (AP) – A crew that specializes in cleaning drug-infested homes is at work in a Wagner home where authorities say a 2-year-old girl was found dead in a closet.

Joe Newcomb with Santi-Kleen Environmental Solutions tells KELO-TV traces of methamphetamine contaminate nearly every surface in the Yankton Sioux Housing Authority home where Taylor and Laurie Cournoyer lived.

Authorities allege the caregivers were using meth and other drugs when the girl died and didn’t report the death for nearly two days. They have pleaded not guilty.

Some people believe meth use has become rampant in the Wagner area. Newcomb says meth might have been manufactured at the home in which the Cournoyers lived for years before they moved in.

Santi-Kleen Environmental Solutions is teaching local workers how to properly clean meth houses.
