A Portsmouth man was sentenced Wednesday to 30 years in prison for his leadership and involvement in a heroin trafficking operation, part of which operated in Suffolk.

Alonzo Outten, 35, ran the operation that was responsible for the distribution of between 30 and 90 kilograms of heroin, according to a news release from the U.S. Attorney’s Office. The drugs had an estimated street value between $1.5 and $4.5 million.

Alonzo’s girlfriend, Latina Latrice Jackson, 27, pleaded guilty in July to assisting in the operation from her home at 6020 Camellia Drive, Apartment B.

According to court documents, she allowed Outten to use her apartment to prepare the heroin for distribution and her vehicle to collect payments for the heroin. He paid her about $400 a month for the use of her apartment and vehicle, and she used the money to pay bills, the court documents state.

Outten and others were indicted on July 8. On July 14, search warrants were executed simultaneously at Jackson’s apartment and 14 other properties in Portsmouth, Chesapeake and Suffolk.

According to court documents, Outten was the leader of the organization from November 2013 to July 2015. He managed six mid-level drug operatives who in turn managed approximately a dozen other individuals that either directly assisted or facilitated the trafficking and distribution of heroin.

Outten supplied kilogram amounts of heroin to at least two Bloods gang sets: the Imperial Gangsta Bloods led by “Godfather” Chris Smith, also known as “Killa,” who pleaded guilty on July 28; and the Gorilla Mafia Piru gang led by Theodore Vann, also known as “Flatline,” who pleaded guilty on June 25.
