Nearly a year after Ariela Mejia-Polanco’s death shocked her loved ones and social media followers, federal prosecutors say her killing was part of a far larger alleged criminal enterprise. On Monday, authorities unsealed a 15-count federal indictment charging 11 alleged members of the Trinitarios street gang with racketeering conspiracy and a series of violent crimes across New Jersey, the Bronx, and the Hudson Valley. Among the killings detailed in the indictment is that of 33-year-old Ariela Mejia-Polanco, who was known online as Ariela La Langosta.
Prosecutors say the defendants are tied to the “Bad Boys 7” set of the Trinitarios gang, which allegedly operated across multiple communities in the tri-state area.
Who Was Ariela Mejia-Polanco?
Mejia-Polanco built a following on social media as Ariela La Langosta. Her death drew widespread attention after she was found dead on the Cross County Parkway in Westchester County.
The case sparked an outpouring of grief online. Nearly a year later, the newly unsealed federal indictment has brought renewed attention to her death as prosecutors outline the alleged criminal enterprise behind the case.
Federal Prosecutors Detail Alleged Gang Enterprise
The indictment alleges the Trinitarios’ “Bad Boys 7” set operated as a criminal enterprise responsible for murder, assault, robbery, carjacking, narcotics trafficking, and wire fraud.
Westchester County District Attorney Susan Cacace addressed Ariela’s death while announcing the charges. “Nearly one year ago, members of a violent criminal gang known as ‘BB7’ murdered a young woman in cold blood on the Cross County Parkway in an attempted carjacking. That woman’s name was Ariela Mejia-Polanco, and her only crime was driving a luxury car in sight of these defendants.”
FBI Assistant Director in Charge James C. Barnacle Jr. said the indictment reflects the agency’s continued efforts to dismantle violent gangs operating across the region.
“Members of the BB7 criminal organization allegedly carried out a campaign of violence that left victims and families suffering unimaginable loss,” Barnacle said. “Today’s outcome sends a clear message: This type of violence will never be tolerated in New York. The FBI New York Safe Streets Task Force remains steadfast in our mission to dismantle violent gangs, protect the American public, and deliver justice for the victims.”
Prosecutors allege Ariela’s killing was carried out in furtherance of the gang’s criminal enterprise. The defendants have been charged with racketeering conspiracy, among other offenses.
Other Killings Named in the Indictment
The indictment also outlines several other killings that prosecutors say were tied to the alleged criminal enterprise. These include the March 30, 2024 killing of Frankelis Tavarez in the Bronx, the July 28, 2025 killings of Gabriel Alvarez and Adam Waldropt in the Bronx, and the Aug. 17, 2025 killing of Alvis Perez-Liriano in Newark.
What Happens Next?
Federal officials are expected to release additional details as the prosecution moves forward. While the indictment marks a significant development in the investigation, the case is still in its early stages. Prosecutors will now present their evidence in court, where the allegations against the defendants will be tested through the legal process.
For those who have followed Ariela Mejia-Polanco’s case, the indictment marks a significant development nearly a year after her death. The case will now move through the federal court system as prosecutors seek to prove the allegations.
