Los Angeles (CNN) -- Michael Jackson's mother says she's hoping Dr. Conrad Murray will get the harshest sentence possible, four years in a state prison, in the death of her son.





"I don't believe that he intended for Michael to die," Katherine Jackson told CNN Monday. "He was just taking a chance."





A jury found Murray guilty of involuntary manslaughter three weeks ago, and Los Angeles Superior Court Judge Michael Pastor set Tuesday for his sentencing.





Pastor, who sent Murray directly to jail after he was convicted this month, has a choice ranging between probation and up to four years in a state prison. But measures to relieve California prison and jail crowding could significantly shorten his time locked up.





Prosecutors successfully argued that Murray's reckless use of the surgical anesthetic propofol to help Jackson sleep, without proper monitoring equipment, led to the pop icon's death.





Testimony during his trial revealed that Murray gave propofol nearly every night in the two months before the singer's death on June 25, 2009, as Jackson prepared for his comeback concerts set for London the next month.





Katherine Jackson and several of her children will be in court for the sentencing Tuesday, but her grandchildren Prince, Paris and Blanket will not. They'll be at school, she said.





She was uncertain whether anyone from the family would speak in court, but she was interviewed by a probation officer who will include her thoughts in the report to the judge, Jackson said.





Murray's elderly mother, Milta Rush, wrote a letter to the judge asking for mercy, saying "his compassion and his soft heartedness for others led to this dilemma."





Prosecutors are asking for the maximum four years behind bars, and they want Murray to pay Jackson's children more than $100 million in restitution. Defense lawyers want probation, not prison time.





Each side will have a chance to present oral arguments Tuesday, but their positions were detailed in sentencing memos filed with the judge last week.





Murray has "displayed a complete lack of remorse" about Jackson's death, and is, "even worse, failing to accept even the slightest level of responsibility," deputy district attorneys David Walgren and Deborah Brazil wrote.





The prosecutors cited Murray's decision not to testify in his own defense, even while he was giving interviews for a documentary that aired days after the verdict.





"In each of these interviews, the defendant has very clearly stated that he bears no responsibility for Michael Jackson's death," the prosecutors said. "Moreover, the defendant has continued to express concern only for his individual plight and portrays himself, not the decedent, as the victim."





"I don't feel guilty because I did not do anything wrong," Murray said in the documentary quoted by the prosecution.





"Finally, the defendant consistently blames the victim for his own death, even going so far as to characterize himself as being 'entrapped' by the victim and as someone who suffered a 'betrayal' at the hands of the victim," the prosecutors said.





Jackson's death came as he was preparing for a series of comeback concerts in London, which the defense argued pressured the singer to seek sleep or risk having the concerts canceled.





The prosecutors contend in their sentencing memo that Murray should be ordered to pay Jackson's three children restitution for the subsequent "wage and profits lost," as provided under California's "victim's bill of rights" law.





The singer's "estate estimates Michael Jackson's projected earnings for the 50-show O2 concert series to be $100,000,000," the prosecutors said.





With nearly $2 million in funeral expenses and 10% interest added each year, the prosecution is asking Pastor to order Murray to pay Prince, Paris and Blanket Jackson more than $120 million in restitution.





While it is doubtful that Murray, who is unlikely to ever practice medicine again, could pay much of that sum, it could prevent him from reaping financial benefits from any books, interviews or film projects in the future.
