A New York police officer who ran a heroin-trafficking ring with her boyfriend out of their Bronx apartment has been found guilty by a federal jury.

Yessenia Jimenez, 32, described as 'a drug dealer in a cop's uniform' by prosecutors, was unanimously convicted on Thursday after a one week trial in a Manhattan court.

The jury heard how she and her boyfriend Luis Soto, 35, stashed kilos of heroin, fentanyl and cocaine inside their Bronx apartment, as well as hundreds of thousands dollars in drug money.

Yessenia Jimenez, 32, was found guilty on Thursday of conspiracy to distribute heroin, possession of heroin and using and carrying a firearm in relation to heroin trafficking

Jimenez and her boyfriend, Luis Soto, turned their Bronx apartment into a drug stash house

Their expansive operation, which spanned Mexico, Boston and New York, began to unravel in January 2018, when authorities seized over $70,000 in cash from a suspected drug dealer in Queens.

A search of the suspect's cell phone revealed the phone number of a person authorities say is a known drug trafficker in Mexico.

Text messages from the Mexican contact contained Soto's phone number.

After federal agents learned of Soto's identity, they conducted surveillance operations outside of his Bronx apartment.

During the course of their investigation, they learned Soto was living with Jimenez, who had been working as an officer for the NYPD since 2015.

In March, DEA and NYPD officers stationed outside the couple's home found them returning at 2.00am from a meeting with a Massachusetts heroin trafficker.

In an effort to explain the NYPD-issue Glock 9-mm and $25,000 cash in her purse, Jiminez told officers she was 'on the job' - or conducting official police business.

The couple were carrying a total of $50,000 cash. Soto was detained, following which agents obtained a search warrant for the apartment.

U.S. Attorney Geoffrey S. Berman said: 'As proven at trial, Yessenia Jimenez, an NYPD officer, trafficked heroin, fentanyl, and cocaine in New York City, a city she took an oath to serve and protect, and used her NYPD service firearm to carry out her drug dealing.

'Simply put, Jimenez was a drug dealer in a cop's uniform. Thankfully, Jimenez now stands convicted and faces at least 15 years in prison.'

Soto and four other members of the operation pleaded guilty.

At the time of the arrest, NYPD Commissioner James O'Neill said in a statement the arrest and allegations are troubling.

'Cops are charged with enforcing the law, not breaking it,' the commissioner said.

'Today's arrest - for serious allegations of trafficking heroin - are troubling.'

Both Jimenez and Soto were charged with conspiracy to distribute heroin, possession of heroin, possession of at least 100 grams of heroin with intent to distribute, and using and carrying a firearm in relation to their heroin trafficking.
