Hartford authorities on Wednesday announced new $25,000 rewards for information leading to convictions in 10 cold case murders. “No cold case is ever closed,” said Lt. Aaron Boisvert of the Hartford Police Department at a press conference at department headquarters. “In many cold case investigations, even a single piece of information can provide critical leads, corroborate existing evidence, or help identify those responsible.” Those with information are encouraged to call either the Hartford Police tipline at (860) 722-8477 or the state’s Division of Criminal Justice Cold Case Unit at (866) 623-8058.
