A cold case from 1971 involving the homicide of Isadore “Izzy” Pacht was assigned to detectives of the 48th Precinct New York City Detective Squad by the Governor’s Office. After 34 years of periodic case reviews at the request of the Pacht family, it remained cold due to outdated, incomplete and inaccurate information included in the original case file. It wasn’t until a detective squad with access to a powerful public records database was assigned to this case in 2005 that it would be solved.
