An evening walk for pizza with her younger sister ended in tragedy for 18-year-old Marilyn Cotto Montanez of Yonkers on April 25, 2019. As the two walked along Morningside Avenue, a single gunshot struck Marilyn in the head; she was later pronounced dead at a local hospital. Her nine-year-old sister witnessed the shooting and was physically unharmed but left with the memory of her sister’s last moments.

Investigators quickly focused on a 15-year-old boy, Jamir Thompson, saying the shooting erupted from a dispute over a gold chain allegedly stolen earlier that day. Authorities say Thompson fired at another male and a stray bullet hit Marilyn. Thompson fled the scene, triggering a manhunt and a reward for information; police warned that anyone harboring him would face prosecution.

If anyone in Yonkers saw Marilyn or her sister that evening, saw the shooting, or has information about Thompson’s whereabouts at the time, please come forward.
