EVART — Six people are in custody after a sexual assault investigation uncovered an active meth lab in Evart.

The investigation began earlier in the week with the arrest of 26-year-old Lake resident Joshua Joseph Letts, a suspect in a third-degree criminal sexual conduct case.

After being arrested on Wednesday, Letts told police there was evidence related to the case at two homes, one in Evart and one in Lake, said Clare County Sheriff’s Det. Sgt. Michael Coon.

“We went with a search warrant for the CSC case to the Evart house and, during the course of the investigation, we found a meth lab,” Coon said.

The house, located on 5 Mile Road in Evart, contained an active, one-pot meth lab. The house in Lake was found to be an active drug house, from which three suspects were buying and selling meth, Coon said.

Two people were arrested in Evart and three were arrested in Lake. None of their names have been released pending arraignments, which are expected on Monday.

Letts remains in Clare County Jail on a $500,000 bond. He is charged with four counts of third-degree criminal sexual conduct. He is a second-time habitual offender.

Traverse Narcotics Team assisted with the investigation and meth clean up. Other assisting agencies included Osceola County Sheriff’s Office, BAYANET, 3rd District Michigan State Police Meth Team, Evart Fire Department and Osceola County Emergency Medical Services.
