The final defendant in a heroin trafficking operation that took place partly in Suffolk was sentenced in U.S. District Court Friday.

Jerald Outten, 26, of Portsmouth, was sentenced to 22 years in prison for his involvement in the operation, which was responsible for the distribution of between 30 and 90 kilograms of heroin with an estimated street value between $1.5 and $4.5 million.

The “Outten Organization” was responsible for at least five non-fatal heroin overdoses in the Hampton Roads area, according to a press release from the office of Attorney General Mark Herring.

The seven co-conspirators were sentenced to a combined 136 years in prison.

Search warrants were executed simultaneously early on July 14, 2015, on 14 properties in Suffolk, Chesapeake and Portsmouth, with more than 250 law enforcement officials involved.

Jerald Outten’s brother, ringleader Alonzo Outten, ran the organization partly from an apartment on Camellia Drive that belonged to his girlfriend, Latina Latrice Jackson, 27, who pleaded guilty to assisting in the operation. She lived at 6020 Camellia Drive, Apartment B.

According to court records, from May to July of this year, Jackson allowed Alonzo Outten to use her apartment and her vehicle to support his operation.

He kept chunks of raw heroin in her apartment, broke it down, cut it to expand its volume and placed it into individual gel caps on her dinner table.

Jackson also allowed Outten to use her vehicle to collect payments for the heroin and sometimes traveled with him as he did so, according to the court documents.

Outten paid Jackson about $400 a month for the use of her apartment and vehicle, and she used the money to help pay bills, the documents state.

According to the court documents, at least five children were present, along with Jackson, when the search warrant was served. Law enforcement officials recovered a diaper bag that contained two digital scales, a coffee grinder used to cut heroin, straight razors, hundreds of gel caps and a chemical agent used to cut heroin for street-level distribution.

The operation was responsible for providing drugs to two violent Bloods gangs, the Gorilla Mafira Piru and Imperial Gangsta Bloods, both of which have been dismantled and prosecuted, according to the U.S. Attorney’s office.

“The excellent coordination between federal, state and local law enforcement agencies was critical in dismantling this group and so many others like them in 2015,” said Dana J. Boente, U.S. Attorney for the Eastern District of Virginia. “This case, and the resources and collaborative efforts used to investigate and prosecute it, is a prime example of the level of commitment and determination we have to combat the heroin crisis in the Commonwealth of Virginia.”

“This case demonstrates the severity and degree to which sophisticated drug operations try to profit off of the addiction, despair and pain of others and threaten the safety of the communities where they operate,” said Attorney General Mark R. Herring. “This outcome demonstrates the power of collaboration and our combined resolve to fight the heroin epidemic that has affected so many people in our commonwealth and throughout the country.”
