These four women were long believed to be the only victims of serial killer Joseph Nassau.

It was because of the alliterative names of his victims that N Neso was given a new name, the alphabet killer.

From his troubled early years, Neso grew up to be a monster who lived a double life.

Publicly, he was a father, a husband, a little league coach, and a photographer.

But behind the facade, he was a sadistic murderer who would stalk, rape, photograph, and then kill women.

For years, the murders of these four women would be the only crimes for which NASO was held accountable.

But these weren't the only ones.

The true extent of Nassau's sinister serial killing spree

would later be brought to light,

not by police, but by a fellow death row inmate.

I'm Emily Campano, and this is the Fox True Crime podcast.

Thank you. podcast. Joseph Neso had long held a fascination with rapists and serial killers, but one criminal was his idol, Carl Chesman. Nicknamed the Red Light Bandit,

Chessman was a convicted robber, kidnapper, and serial rapist. After Nassau became his pen pal,

he invited him to attend his execution in 1960. Investigators believed that by killing women with double initials, Nesso was paying homage to Chesman.

While in prison, Nesso began confiding in a fellow death row inmate,

a man by the name of William Nogara.

Naseau would frequently brag about his despicable crimes, including ones for which he had not

been convicted of. But unbeknownst to him, William kept a log of these details determined

to help bring justice to the case. To do so, he needed help from the outside. That's when he contacted

Ken Maines, a retired FBI task force investigator and cold case detective.

Ken Mainz joins me now to talk about the formation of this unlikely team and their vital work uncovering the crimes of Nassau, as explored in the new docu series Death Row Confidential Secrets of a Serial Killer.
