REDWOOD CITY -- Calling the defendant's crime the "most violent and gratuitous" murder he's seen in 25 years on the bench, a judge on Tuesday sentenced Tyler Hutchinson to life in prison without the possibility of parole for the beating death of an elderly Belmont man.

Defense attorneys asked for a sentence of 25 years to life, citing Hutchinson's history of mental illness, but San Mateo County Superior Court Judge Mark Forcum imposed the stiffer sentence, saying he was stunned by the 25-year-old defendant's lack of remorse.

Family members of Albert Korn, whom Hutchinson beat to death during a 2009 home-invasion robbery, did not address the court and declined to make a statement after the hearing. But deputy district attorney Morris Maya delivered a scathing assessment of the perpetrator, a transient whom the defense has characterized as schizophrenic.

"It is quite frankly an evil heart and an evil mind that was behind the killing in this case," said Maya, adding that Hutchinson, despite his mental healthy problems, understood the nature of his crime.

Hutchinson, dressed in red jail clothes signifying his status as a high-risk prisoner who is kept apart from other inmates, merely shook his head of unkempt hair when Forcum asked if he wanted to speak. In a probation report, however, Hutchinson indicated no contrition for his actions, Forcum and Maya said.

"He's dead. Everybody dies," Hutchinson told a probation officer. "I'm gonna die. You're gonna die. I don't care."

Hutchinson broke into Korn's Hallmark Drive home through a window on June 2, 2009, and brutally beat him before escaping in the victim's Jaguar. Korn, 88, died two weeks later at Stanford Hospital.
