Sweetwater County Sheriff Mike Lowell says investigators have arrested a father and daughter on methamphetamine and marijuana charges.

The sheriff says a Rock Springs undercover drug sting operation led to the arrest of 68-year-old Robert Perry, and his 44-year-old daughter Tammra Perry, both of Gillette, Wyo.

The sheriff says a search of their motel room found over an ounce of methamphetamine, as well as packaging materials, digital scales and other items that would be used to sell meth. A small amount of marijuana and some cash were also found, according to Lowell.

Robert Perry is being charged with possession of a controlled substance with intent to deliver as well as felony possession of a controlled substance and misdemeanor drug possession for the pot. Mr. Perry could be sentenced to up to 27 years in prison and fined up to $40,000 on the meth charges.

Tammra Perry is so far facing charges of possession of a controlled substance as well as two local bench warrants and some traffic offenses.

Her bond has been set at $1,000 while her father's bond is $50,000. As of Wednesday evening both were being held in the Sweetwater County Jail.
