Exact moment mass murderer gives himself away during police interview

The exact moment a mass murderer gave himself away during a police interview can be seen in chilling footage that just re-emerged on social media.

In April 1996, Martin Bryant murdered 35 people and injured a further 23 during a shooting spree in Port Arthur, Tasmania.

The incident was so horrific that it became known simply as the Port Arthur massacre and led the Australian government to introduce extensive extra measures on firearms ownership.

Bryant was given 35 life sentences and an additional 1,652 years, with no possibility of parole, and he remains in Risdon Prison in Hobart.

In the resurfaced video, which re-appeared on TikTok, Bryant is shown answering questions asked by police investigators, but briefly lets his guard down when he thinks that the tape is no longer recording.

The clip was originally shown on an Australian TV show about his crimes.

When he appears to let down his guard, Bryant seems to admit to the killings freely, even chuckling while doing so.

Bryant told the police officers: "I'm sure you'll find the person that caused all of this."

He then points to himself and mutters 'me' underneath his breath.

One of the police officers then responds: "I don't find that a very funny statement at all, Martin, to be quite honest."

The grinning Bryant then says: "You should have put that on recording."

That's when the police officer confirms: "Oh, it's still recording at the present stage."

If you're interested in learning more about Bryant and his horrendous crimes, a documentary was released in Australia in 2021 that addressed not only what happened at Port Arthur, but also alleged that Bryant was responsible for two further murders: his father and a wealthy lover.

7News Spotlight: Martin Bryant's Dark Secrets, which aired on in May 2021 on 7News, claimed to have spoken to new witnesses and found new documents relating to the case, and also may suggest that Bryant's atrocities at Port Arthur could have been avoided if the authorities had acted.

Investigator Denham Hitchcock believes that he uncovered evidence that proves Bryant killed his dad Maurice, as well as linking him to a car crash that killed Helen Harvey, a wealthy 54-year-old woman, in October 1992.

The crash occurred when the car Harvey was driving veered into oncoming traffic. Bryant himself was also hospitalised, and briefly investigated, but the death was eventually ruled to have been an accident.

Then, after Maurice moved into a farm owned by Harvey and Martin while the latter recovered from the accident at the family home, he was found dead in a dam near to the farmhouse with a weight around his neck.

Police described the death as 'unnatural' and ruled it a suicide, while Martin inherited his father's superannuation fund, which was worth around $250,000 (Australian Dollars).
