jury. 

Rosini tightly pursed her lips and shook her head in a clear show of disgust and disbelief as Marcelin spoke, while her co-counsel, Assistant D.A. Viviane Dussek, rolled her eyes.

Marcelin was initially sentenced to life without parole for the 1963 shooting of girlfriend Jacqueline Bonds, after the jury couldn't agree on imposing the death penalty.

Marcelin shot Bonds in the hallway of an Harlem apartment, then chased her into a bedroom and shot her again, according to court filings.

After a change in state law, Marcelin was released on lifetime parole in 1984.

A year later, he stabbed to death another girlfriend, Anna Laura Serrera Miranda, dumping her remains by Central Park in October 1985. Marcelin pleaded guilty to manslaughter in that case.

When a judge asked,  You kept stabbing her so she would stop screaming?  Marcelin responded,  It was just - I was doing it, you know. 

At a June 25, 2019, parole hearing, Marcelin vowed,  I give you my word, I will never re-offend. 

He broke that vow less than three years later after he became infatuated with Leyden. He created multiple Facebook accounts, all with her photo as his profile picture. Leyden was down on her luck. She lost her jewelry business, became estranged from her daughter, and wound up in a homeless shelter. But she was getting her life back together, prosecutors said.

All that ended on Feb. 27, 2022, when Leyden walked into Marcelin's apartment on Pennsylvania Ave. to visit him and never came out.

After the e-bike rider found her torso days later on March 3, police discovered black plastic garbage bags in Marcelin's apartment with Leyden's thighs, hand, arm and head inside. Marcelin also stuffed part of the victim's left leg into his electric wheelchair and went shopping before disposing of the limb, prosecutors allege.

Assignment - DISMEMBER

The victim's right leg, left arm and left hand were never recovered.

 The brutality of this shocking crime is almost beyond words,  Brooklyn D.A. Eric Gonzalez said Wednesday.  This defendant committed a horrific murder that took Susan Leyden's life and inflicted unimaginable pain on her family and loved ones.
