A 54-year-old Dallas man described by federal prosecutors as a career criminal who ran a rampant drug distribution ring out of a blighted motel near Dallas Love Field has been sentenced to 25 years in federal prison, authorities announced Thursday.

Fentanyl ring dismantled Earnest Ray Miller, also known as "Q," was sentenced July 24 by U.S. District Judge Karen Gren Scholer to 300 months in prison on drug and firearm charges.

Federal authorities said Miller, a multi-convicted felon, operated his drug trafficking network out of multiple rooms at the former Cole Manor Motel, located at 7002 Harry Hines Blvd. The motel, long regarded by local officials as a notorious hub for violent crime, drug dealing, and prostitution, was demolished on June 17 following the federal investigation and a criminal nuisance lawsuit filed by the City of Dallas.
