I am from Missouri. Not close to Senath though. But I didn't read a drug squad was on the case. I do know we have Major Case Squads that include members from different agencies. So I think it is possible a drug investigator is a member of the team. Drugs and especially meth is always a possibility. jmo
The Senath Police Department along with the FBI Task Force, Dunklin County Sheriff's Office, Missouri State Highway Patrol, Kennett Police Department and the Bootheel Drug Task Force are investigating the case
