Chilling black and white pictures of 1920s crime scenes reveal the Big Apple's bloody history

The New York City Police Department has opened its vaults and released some of the most bloodcurdling images of the 20th century: its catalog of killers and their victims.

The 1,326 police evidence photographs are now available on the Department of Record’s website, sure to inspire more than a few nightmares.

The images were taken between 1915 and 1930 and show dozens of dead bodies, grieving mothers and portraits of the cold-blooded murderers themselves. However, MailOnline spoke to a retired detective who saw something different: just another day in the life of an NYPD officer.
