An Anchorage resident arrested in 2014 for operating a large drug ring in the Mat-Su and Fairbanks was sentenced Monday to 22 years in prison, according to a press release from the Alaska State Troopers.

Seneca Neal, 37, has been held without bail since his arrest on Nov. 30, 2014.

Investigators with the Statewide Drug Enforcement Unit (SDEU), along with multiple other agencies, discovered Neal was distributing large amounts of heroin and other drugs throughout the Mat-Su and Fairbanks.

In 2014, authorities seized about $232,000 worth of brown heroin, bath salts, marijuana and over $8,000 in cash as part of their investigation, AST spokesperson Megan Peters wrote in the release.

Neal was found guilty of conspiracy to distribute more than a kilogram of heroin, distribution of over 100 grams and possession with intent to distribute.

Authorities seized over 700 grams of heroin following multiple raids in 2014, according to Peters.
