Nicholas Guido, 26, was shot dead on Christmas Day 1986 while sitting in his new car outside his mother’s home in Park Slope, Brooklyn. He was a telephone installer with no ties to the criminal underworld. His mother discovered him after hearing gunfire while she was inside washing dishes after their Christmas dinner.

Reports say the killing was a case of mistaken identity: Guido shared a name with a Gambino associate involved in an attempted hit on Lucchese underboss Anthony Gaspipe Casso. Investigators later concluded that information supplied to Casso by two NYPD detectives, Louis Eppolito and Stephen Caracappa, led a hit team to the innocent Guido.

Eppolito and Caracappa were arrested in 2005 and convicted in 2006 on racketeering charges that included the murder of Nicholas Guido; both received life sentences. Guido’s family later sued the city and in 2015 agreed to a five-million-dollar settlement.

Did anyone in Park Slope at the time recall unusual activity or vehicles near Guido’s mother’s home that day?
