West Haven Man Convicted of Drug Dealing in 2019 Sentenced to Additional Prison Time for Violating Supervised Release
David X. Sullivan, United States Attorney for the District of Connecticut, today announced that DEVELL CONLEY, 39, recently residing in West Haven, was sentenced yesterday by U.S. District Judge Janet C. Hall in New Haven to 21 months of imprisonment for violating the conditions of his supervised release that followed a prior conviction for distributing narcotics.
According to court documents and statements made in court, in May 2019, Judge Hall sentenced Conley to 78 months of imprisonment and three years of supervised release for distributing fentanyl, heroin, and crack cocaine. The investigation revealed that Conley had provided drugs to an adult female shortly before her death from an overdose. Conley was released from prison in January 2023.
In August 2023, while on supervised release, Conley was arrested by New Haven Police for possession with intent to distribute a controlled substance. In November 2024, he was arrested by West Haven Police for sale of a narcotic substance. He subsequently pleaded guilty in Connecticut Superior Court in both cases, was sentenced to 18 months of imprisonment for the West Haven offense, and is awaiting sentencing for the New Haven offense. While on supervised release, Conley also repeatedly tested positive for controlled substances, was found in possession of a device used to defeat a drug test, failed to notify his federal probation officer about his change of residence, and provided fake paystubs to his federal probation officer in an attempt to show proof of employment, all in violation of the terms and conditions of his supervised release.
After Conley admitted to the violations in court yesterday, Judge Hall revoked his supervised release and sentenced him to 21 months of imprisonment with no supervised release to follow. Conley has been detained in federal custody since January 29, 2026.
The case was prosecuted by Assistant U.S. Attorney Neeraj N. Patel.
