A man jailed for killing three people as he drove at 90mph down a busy shopping streetin his two-ton SUV has been found dead in his prison cell in Austria.
Alen Rizvan Rizvanovic, 33, had apparently committed suicide after seven years behind bars.
His body was found on 23rd September as guards at the Stein Correctional Facility, in Krems an der Donau checked his single cell.
Austrian media says they also discovered a note close to his corpse saying: “I am innocent.”
The country’s Ministry of Justice later confirmed his death saying: “We can confirm that a suicide occurred in the Stein prison.”
They added: “Please understand that for data protection reasons we can not communicate any further details about the incident.”
Krems Public Prosecutor’s Office has ordered an autopsy to establish the cause of death.
Rizvanovic had been serving a life sentence after being found guilty of killing three and trying to murder 108 others in 2015 .
Prosecutors said he deliberately ran his Daewoo Rexton SUV into crowds of shoppers in Graz at speeds of up to 90mph.
He then climbed out of the vehicle and started randomly stabbing bystanders, including elderly people and police officers.
His dying victims included a 28-year-old man, a 25-year-old woman, and a boy aged just four.
Oddball Rizvanovic appeared at his trial dressed head to toe in white and claimed he had panicked when he heard what he thought were gunshots.
He had arrived in Austria with his parents as refugees from the Bosnian War in 1993.
Rizvanovic had been under a restraining order and was banned from approaching his wife and two young children after he was reported for domestic violence.
He was caught soon after the carnage and told police he felt persecuted by ‘Turks’.
In 2016 Rizvanovic was sentenced to a life behind bars in prison for a planned mass murder after a Graz district court jury unanimously declared him sane.
