Harvey Marcelin

Harvey A. Marcelin (born May 21, 1938) is an American serial killer of women.

Marcelin has been convicted of killing three women, including two former girlfriends, in 1963 and 1986; his most recent conviction was in May 2026.

Marcelin came out as transgender and began transitioning to a woman in 1993. However, in early 2026, he began re-identifying as a man. According to later interviews, Marcelin was spoiled by both of his parents and grew up in a relatively stable environment. Not long after, he was admitted to a psychiatric hospital in the summer of that year for evaluation on behalf of Catholic Charities USA. Tests conducted during this time established that he showed signs of chronic schizophrenia, delusions and a paranoid personality. When asked why he did it, he claimed that he killed Bonds out of jealousy, since Bonds was beautiful and popular and Marcelin did not want her to be with other men.

In early 1985, he met 29-year-old Anna Laura Serrera Miranda, a heroin addict and prostitute who soon became his lodger and roommate. At the time she met Marcelin, Leyden suffered from an undisclosed mental illness and was addicted to drugs, but was formerly a successful entrepreneur who owned a jewelry store in Fort Lee, New Jersey, which she had to abandon in the late 2010s due to her declining mental health.

On the following day, Marcelin was arrested at the apartment following a police search which uncovered Leyden's severed head, a power saw, and bloody sheets. Police also reviewed surveillance footage that covered the entryway of the apartment building where Leyden and Marcelin lived, with the footage showing that Leyden was last seen alive entering the building on February 27.

Charges and theories about motive On March 30, 2022, Marcelin was charged with second-degree murder and concealment of a corpse, to which he pleaded not guilty. An examination of Marcelin's social media accounts revealed that he initially established contact with Leyden in 2019, and throughout 2020 and 2021, he repeatedly used Leyden's photos as his social media profile picture. In October 2021, just months before Leyden's murder, Marcelin responded to a comment made by Leyden by simply saying "Love personified".

Third trial and conviction Marcelin's trial for the murder of Susan Leyden began on April 20, 2026. It ended in May 2026, after Marcelin began identifying as male again, and with another conviction for murder. On June 10, 2026, Marcelin was sentenced to life imprisonment without the possibility of parole.
