A Bridgeport man has been arrested for distributing heroin that lead to an overdose death in Seymour this summer.  Seymour Police responded to a home and found a 29-year old man unresponsive, without a pulse.  Investigators seized the victim's cellphone, multiple folds of suspected heroin marked with two different brand stamps, and other drugs.  They determined that 23-year old Richard Estaba supplied the heroin.  Investigators were able to make a controlled substance purchase from Estaba of the same brand.  When he was arrested yesterday, Estaba was in possession of 400 folds of heroin and $1,300 in cash.
