A man who killed his father and tried to kill his mother ‘did not regret’ his crimes, a report has said.
Lukasz Lukasik had admitted murdering his father Jerzy, attempting to kill his mother Maria and hurting his sister Monica in Selby on 29 December 2020.
It happened in a property on Finkle Street.
Lukasik pleaded guilty to the crimes by video link to Leeds Crown Court on 14 May 2021 from prison in HMP Hull.
At around 4.52am on 27 May, he was found hanging in his cell. Paramedics were called and he was pronounced dead at 5.32am.

Now the Prisons and Probation Ombudsman has released a report into his death.
It said staff were unaware that Lukasik had changed his plea to guilty.
The report says: “Prison and healthcare staff were unaware of the change in his circumstances and our investigation found that Hull did not have a standard procedure for assessing whether there had been a change in risk for prisoners after attending video link court hearings.
“Prison staff initially completed regular welfare checks and there was little to indicate to staff that he was at imminent risk of suicide.
“There was a 14-minute delay between staff being unable to see Mr Lukasik in his cell and returning to check on him again.
“An emergency code was not called for a further seven minutes. Although this did not affect the outcome for Mr Lukasik as he had been dead for some time, it could make a critical difference in future medical emergencies.

“The clinical reviewer concluded that the clinical and mental healthcare Mr Lukasik received at Hull was not equivalent to that which he could have expected to receive in the community.”
Earlier a nurse at HMP Hull had completed his initial health screen. She found he was a Polish speaker with good English who had a history of substance abuse.
He had dislocated his shoulder while in police custody.
“The nurse noted that he was not at risk of suicide or self-harm,” the Ombudsman said.
“Mr Lukasik said he was aware that he was facing a long prison sentence and did not regret his offence.”
The report acknowledged that the prison faced “significant difficulties” at the time due to Covid.
The Ombudsman recommended that staff should speak to a prisoner following a court appearance by video link and consider whether the risk to themselves has changed.
