NEW HAVEN \u2014 A city man who is suspeted of dealing fentanyl to a Wallingford man who died of an overdose was arrested by federal authorities, according to a release. Alex Borrero, also known as \u201cRed,\u201d 50, of New Haven, is charged with possession with intent to distribute, and distribution of, fentanyl and heroin, federal authorities said in the release. If convicted, Borrero faces up to 20 years in prison. The arrest is part of an ongoing statewide \u201cinitiative targeting narcotics dealers who distribute heroin, fentanyl or opioids that cause death or serious injury to users,\u201d the release said. Following his appearance Tuesday before U.S. Magistrate Judge Sarah A.L. Merriam in New Haven, Borrero was released on $50,000 bond into an inpatient drug counseling program, the release said. The charges against Borrero stem from an incident on Feb. 28, during which the Wallingford Police Department and emergency medical personnel responded to a report of the untimely death of a 25-year-old male at a residence in that town, the release said. Officers seized drug and non-drug evidence, including the victim\u2019s cellphone and six empty wax folds bags that contained a white powder residue and the state Office of the Chief Medical Examiner determined the victim\u2019s death was \u201ccaused by a combination of fentanyl and alprazolam (Xanax),\u201d according to the release. Authorities allege Borrero was the source of the fentanyl involved in the victim\u2019s overdose death. The investigation also involves an overdose death of a 31-year-old male in Branford on May 18, the release said. When he was arrested, Borrero allegedly had 30 grams of heroin and about $1,900 in cash on him, according to authorities. The case is being investigated by the Drug Enforcement Administration\u2019s New Haven Tactical Diversion Squad, Wallingford Police Department and Branford Police Department. The Tactical Diversion Squad includes members from the New Haven, Hamden, Greenwich, Shelton, Bristol, Vernon, Wilton, Milford, Monroe and Fairfield Police Departments, and the Connecticut State Police.
