LOS ANGELES — A judge today sentenced Dr. Conrad Murray to four years behind bars — the maximum punishment possible — for his part in Michael Jackson’s death, saying the doctor’s role in the singer’s fatal overdose was “money-for-medicine madness.”

In blistering and lengthy remarks, Superior Court Judge Michael Pastor lambasted Murray for failing to express any remorse for the pop star’s death and suggesting in a recent documentary that Jackson bore responsibility for his own demise.

“Talk about blaming the victim,” Pastor said. “Not only isn’t there any remorse, there is umbrage and outrage on the part of Dr. Murray against the decedent.”

Pastor denied the defense’s request for probation.

“The fact remains, Dr. Murray is offended that (his) patient died,” Pastor said in a downtown Los Angeles courtroom. And Murray remains a danger to the community, he said.

Murray did not speak before Pastor issued his sentence.
