Chilling tweet Japan knifeman who wanted 'to rid world of disabled people' sent just minutes after he hacked 19 to death at disabled care home he was sacked from

The crazed knifeman who hacked 19 people to death at a care home in Japan because he wanted to ‘get rid of the disabled from this world’ is believed to have sent a chilling tweet just minutes after the attack. Satoshi Uematsu, 26, broke into the centre by smashing a window with a hammer, killing 19 people and seriously injuring 26 people as they slept, in what has
been deemed the country's worst mass murder since World War II.

He went into the Tsukui Yamayuri En centre in Sagamihara, outside of Tokyo, brandishing a knife at around 2.10am and police were called at 2.30am local time.

At 2.50am a picture was published by a Twitter account, named by Japanese media as belonging to Uematsu, showing a man with blond hair, wearing a suit, grinning alongside a message in Japanese which reads: 'May there be peace in the world'.

In English he added the words: 'Beautiful Japan!!!!!!'. 

Police were first called to the scene after residents saw a man with blond hair armed with a blade in black clothes in the centre's grounds.

Uematsu, who is a former employee at the care centre, was arrested after he walked into a police station 30 minutes after the gruesome attack and stated 'I did it'.

Japanese newspaper Asahi Shimbun reported that the suspect told police: 'I want to get rid of the disabled from this world.'

Kyodo news service has released a letter that Uematsu tried to present to Tadamori Oshima, the speaker of the lower house of Japan's parliament, in February calling for euthanasia of disabled people.

In it, Uematsu described detailed plans on how he planned to carry out such an attack during the night when there were few staff working. He wrote he would then turn himself in to the police. 

Uematsu said that by killing the disabled he would stimulate the world economy and maybe even prevent a World War III.

'Now is the time to carry out a revolution and make an inevitable but tough decision for the sake of all mankind,' Uematsu wrote.  

'My goal is a world in which, in cases where it is difficult for the severely disabled to live at home and be socially active, they can be euthanized with the consent of their guardians,' the letter reportedly said. 

After he attempted to deliver the letter in February, he was taken to hospital but released about two weeks later. 

Earlier disturbing tweets on the account believed to belong to Uematsu have also been uncovered. 

On February 19 - believed to be around the time Uematsu was sacked from the care facility - he wrote: 'I may be arrested'.

On January 20, he said: 'I have been found out at the company. I want to survive this with a smile. I will do my best as a 25-year-old!!'After the Munich massacre on July 23 that left nine people dead, Uematsu allegedly wrote: 'It would have been fun if it had been a toy.'
