A convicted drug dealer has been sentenced to 99 years in prison for selling less than an ounce of cocaine to a North Texas law enforcement officer.

Nathaniel Washington was convicted of delivery of a controlled substance for the June 2012 sale to an undercover Arlington police officer.

Prosecutors in Fort Worth on Thursday said Washington, with a history of drug offenses, told the officer that he could also provide marijuana and methamphetamine. Washington was busted following the $450 transaction.

Jurors on Wednesday sentenced the 50-year-old Washington as a habitual offender. Records show Washington in 1990 was sentenced to 50 years in prison for dealing drugs.

“This man had an extensive criminal history and had already been convicted of selling drugs once before,” said prosecutor Taylor Ferguson. “Enough is enough. Drug dealers will not be tolerated in Tarrant County.”

Washington must serve a quarter of the 99-year term before being eligible for parole.
