Violent Waterbury Gang Member Sentenced to 35 Years in Federal Prison (DOJ)

DAYQUAIN SINISTERRA, also known as "Quan," 27, was sentenced today by U.S. District Judge Kari A. Dooley in Bridgeport to 420 months of imprisonment, followed by three years of supervised release, for offenses stemming from his participation in the 960 gang, a violent Waterbury street gang.

Today's announcement was made by Vanessa Roberts Avery, United States Attorney for the District of Connecticut; Maureen T. Platt, State's Attorney for the Waterbury Judicial District; Robert Fuller, Special Agent in Charge of the New Haven Division of the Federal Bureau of Investigation; James Ferguson, Special Agent in Charge, ATF Boston Field Division; and Waterbury Police Chief Fernando C. Spagnolo.

According to court documents and statements made in court, in an effort to address drug trafficking and related violence in Waterbury, the FBI, ATF, and Waterbury Police have been investigating multiple Waterbury-based groups, including the 960 gang. On September 14, 2021, a federal grand jury in Hartford returned a 36-count indictment charging Sinisterra and 15 other 960 gang members with racketeering, narcotics trafficking, firearm possession, murder, attempted murder and assault, and obstruction of justice offenses.

On March 13, 2024, Sinisterra pleaded guilty to one count of racketeering conspiracy, six counts of attempted murder and assault with a dangerous weapon in aid of racketeering, and three counts of carrying and using a firearm during and in relation to a crime of violence.

Sinisterra specifically admitted that he and other 960 members were engaged in violent activity and conspired to shoot and murder members of rival gangs, including:

• On September 21, 2018, in retaliation for the murder of an associate, Sinisterra and other 960 members participated in drive-by shootings of occupied residences on Lounsbury Street and Scott Road in Waterbury.
• On October 6, 2018, in a drive-by shooting, Sinisterra and other gang members attempted to murder individuals believed to be members of a rival gang, which resulted in gunshot wounds to an individual.
• On October 11, 2018, in an effort to murder rival gang members, Sinisterra and other gang members participated in a drive-by shooting that resulted in the death of an innocent bystander, 30-year-old Fransua Guzman, and the paralysis of a second victim.
• On November 1, 2018, Sinisterra shot a rival gang member.
• On November 18, 2018, Sinisterra and other gang members participated in a drive-by shooting of rival gang members, which resulted in gunshot wounds to two individuals.

Sinisterra has been detained since November 21, 2018.

This investigation has been conducted by the FBI's Northern Connecticut Gang Task Force, Waterbury Police Department, ATF, and U.S. Marshals Service, with the assistance of the Southington Police Department, Watertown Police Department, New Milford Police Department, Connecticut State Police, Connecticut Department of Correction, Connecticut Forensic Science Laboratory, and the DEA Laboratory. The case is being prosecuted by Assistant U.S. Attorneys Geoffrey M. Stone, John T. Pierpont, Jr. and Natasha M. Freismuth, and Supervisory Assistant State's Attorney Don E. Therkildesen, Jr. and Deputy Assistant State's Attorney Alexandra Arroyo, who were cross-designated as Special Assistant U.S. Attorneys in this matter.

This prosecution is a part of the Justice's Department's Project Safe Neighborhoods (PSN) and Organized Crime Drug Enforcement Task Forces (OCDETF) programs.

PSN is a program bringing together all levels of law enforcement and the communities they serve to reduce gun violence and other violent crime, and to make our neighborhoods safer for everyone. In May 2021, the Justice Department launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results.
