Calcasieu sheriff's officials patrolling the Anthony Ferry Boat Launch in Sulphur on Tuesday spotted three people cooking what they suspect was speed.
Arrested were Larry W. Cain, 30, Melinda L. Cain, 29, and Jeremy P. Broussard, 40, all of Sulphur. Officials say the trio was in the process of manufacturing methamphetamine.
Detectives said chemicals found the scene were consistent with creation or operation of a clandestine lab. Deputies also recovered a small amount of meth in Broussard's wallet, a sheriff's report said.
All were booked into the Calcasieu Correctional Center and charged with creation/operation of a meth lab. Broussard was also charged with possession of CDS II (controlled dangerous substance); and possession of marijuana. Larry Cain was also charged with possession of marijuana.
Judge David Ritchie set Larry Cain's bond at $110,000, Melinda Cain's bond at $10,500, and Broussard's bond at $65,500.
Miller Environmental was called to dismantle and clean up the meth lab.
