Who was the New York Zodiac killer, what happened to him and is he still alive?

Catching Killers has returned for a third season on Netflix, examining shocking murder cases in America. One of those featured in the latest instalment is the New York Zodiac Killer.

Not to be confused with the actual Zodiac Killer - who was based in San Francisco and never actually found. While inspired by the original murderer, New York's Zodiac Killer was eventually caught and jailed.

Heriberto Seda, a Brooklyn native, shot and killed three people and injured six others, leaving four of them in a critical condition. Described as a longer who was obsessed with astrology, Heriberto was expelled from school as a teenager for bringing a pistol with him.

He was just 23 years old when he shot his first two victims in March 1990, who fortunately survived. And, like the original Zodiac Killer, Heriberto would send taunting messages to the police and media after each crime, which included International maritime signal flags.

These were decoded and his letters claimed he was choosing victims based on their zodiac signs. He also boasted that he'd never get caught, as he was using an improvised firearm which meant the bullets wouldn't be marked, so he couldn't be traced.

A couple of months after his first two shootings, he killed his third victim, who was shot in the back and later died in hospital. Meanwhile the fourth victim, who was attacked later on in the same year, survived.

He struck again in 1992, shooting his next victim twice and fatally stabbing her more than 100 times. He waited another year until he attacked two more victims - one was shot in the head
