EX-ADA OFFICER DRAWS TERM FOR DRUG CRIMES -- FORMER ASSISTANT CHIEF
PLEADS GUILTY

Ada: Phone tap broke case MUSKOGEE -- A former Ada assistant police
chief was sentenced Wednesday to 61/2 years in federal prison for two
drug convictions. Dennis Edmond Corvin, 40, pleaded guilty in August
to having a gun while drug trafficking and establishing a drug
manufacturing operation.

He was sentenced in federal court in Muskogee.

Corvin was arrested in February after the Pontotoc County District
Attorney's Drug Task Force learned that he was involved in a
methamphetamine manufacturing ring.

Corvin, then the security manager at the Ada Wal- Mart, allowed one
of his partners to come in the store and steal lithium batteries.
Lithium strips in the batteries are used to make methamphetamine.

The conspiracy was uncovered when investigators tapped Corvin's phone
and recorded his conversations with a confidential informant.
Investigators learned the ring had operated for at least seven
months, court records showed.

The group had been making methamphetamine at several Ada locations,
as well as in a home in Stonewall. Court records showed one member of
the drug ring went as far away as Shawnee to steal chemicals.

A search of Corvin's home revealed drugs, firearms and items used to
make methamphetamine. Interviews with informants indicated Corvin was
not only a maker of methamphetamine but also a frequent user, court
records state.

Corvin took the Wal-Mart job after retiring from the Ada Police
Department in 1999. He had been on the police force for more than 20
years.
