GILLETTE - An investigation that began last week in Sheridan led to methamphetamine busts here and in Cheyenne, police said.
The state Department of Criminal Investigation said the arrest April 25 of Joseph Mitchell Casey, 29, of Sheridan, led to the other two busts.
Casey was charged with operating a clandestine methamphetamine lab after searches of his home and vehicle allegedly uncovered a quarter ounce of meth and meth-making materials.
The day after his arrest, Casey's sister, Tracy Lain Boone, 31, and Donald Charles Jossens, 33, were arrested in Gillette on drug and child endangerment charges. Police said they found cash, drug ledgers, scales, packaging material and 10 ounces of meth during a search of Boone's home.
That same day, Brenda Lois Palmer, 65, of Camp Verde, Ariz., was arrested at a McDonald's restaurant in Cheyenne. Police said a search of her vehicle turned up 11 ounces of meth, along with drug paraphernalia. Police said Palmer's arrest resulted from information obtained in the other two investigations.
