THE DISPATCH

The Beginning

3X was a self-named double murderer whose cryptic and threatening messages sent panic into the streets of New York in 1930. He claimed of being a Russian spy, and was never tracked down nor identified.

Chain Murders

Serial killers have been around for hundreds of years. Each era had their own way to describe sequential and related murders. In 1930s and 1940s USA, they were called Chain Murders, because they were linked together.

The Murders

The bullet-ridden body of Joseph “John” Mozynski was found by passing motorists on June 13, 1930. Police also found a woman’s bloodstained coat on the passenger side of his car. Police tracked down and questioned Catherine May, a 19-year-old woman who was with Mozynski the night he was killed. For two years, May had been having an affair with the married father of two, and told police she and Mozynski were on a “secret love tryst” that night.

May told police the gunman did not say a word before shooting Mozynski and rifling his pockets. The killer then forced May, at gunpoint, to get on a streetcar and leave the area. Before she left, he gave her a note, with Mozynski’s name on it in red ink, and a circled 3X. Police said they did not believe May. It is noted that Mozynski is also spelled Moyzysky and Mozynsky.

The Story Changes

Survivor Catherine May told police she did not recognize the killer. However, under intense interrogation, she gave police the name Stephen Lombardo. The 19-year-old then repudiated the story and said the murderer was a man she had met a number of times, but did not know his name.

She later told press “I was tired of being questioned, so I made up the Lombardo story. I never knew anybody by that name.” It eventually came out that a man in a black suit, bow tie and black fedora had demanded Mozinksy’s license before shooting him.

Police received a tip that Joseph Moisette, who lived in the same area as the incident, was the killer. He was arrested by police while on a California-bound train. He was going to attend his mother’s funeral. Moisette was released by police. Police also theorized Joseph Moyzynski was murdered as part of a bootlegging war.

The killer of Mozynsky sent a letter to a New York newspaper, boasting about the murder and claiming he would kill again. He signed the letter with an inverted and underlined “V” and the symbol “3X”.

Twelve hours later, on June 17, 1930, Noel Sowley was shot dead behind the wheel of his Plymouth roadster. Sowley had been on a date with Betty Ring, the daughter of a police officer. She witnessed the murder and later gave police a graphic description.

Ring described a “deaconish-looking man” who took Sowley’s license and shot him in the head. The killer then gave her a piece of paper. On it was Sowley’s name in red ink and a circled 3X. He led Ring to a bus, so she could go home. Her husband would later use this affair to successfully petition for a divorce.

Sowley had been shot in the head and discovered the next morning by a farmhand. The radio salesman was 25 years old. The killer had clipped a newspaper article about Mozyski’s slaying, and laid it on the victim’s lap.

In his letter to the newspaper, 3X said there were fourteen more people to die.

Letters to Media

On October 17, 1930, newspapers reported that the 3X killer, as he had called himself, had sent a letter to police. In it, he said “I’m back. I will pay every cop a visit.” More than 200 detectives were brought into a manhunt for the killer. Over the next number of months, police and newspapers would receive more letters threatening murders. Almost 1,000 extra police officers were detailed to Queens.

At one point, an officer was cleaning his gun in the locker room of the Queen’s Station House. The next day he received a letter signed by 3X, stating “I saw you cleaning your gun last night. I hope you didn’t expect to shoot me. You will never find me.”

For the next year, hundreds of letters would be received, but almost every single one was deemd a hoax.

Last Letter

The last letter officially ascribed to 3X was received October 22, 1931. In it, the killer threatened to kill three men at once. He said he might use poisoned darts and a blowgun, or some mysterious “very old Hindu trick.” After this note, he was not heard from again.
