LOS ANGELES (AP) — The doctor convicted of killing Michael Jackson was released from jail Monday after serving nearly two years of a four-year sentence.

Conrad Murray was released from a downtown Los Angeles jail at 12:01 a.m., according to the sheriff's office. A change in California law allowed his incarceration time to be significantly cut down.

"He was elated to be out of there," Murray's attorney Valerie Wass said. She said the former physician plans to spend time with his girlfriend and children and to readjust to his life outside jail.

The former cardiologist was convicted in 2011 of causing Jackson's death in June 2009 by providing the superstar with an overdose of the powerful anesthetic propofol as a sleep aid. Jackson was in the midst of preparations for a series of comeback concerts and Murray was serving as his personal physician.

Murray's prospects are uncertain: At age 60 his license to practice medicine has been suspended or revoked in three states and his face and name are well known due to his association with Jackson and his highly publicized involuntary manslaughter trial.

Wass said Murray did a lot of writing while incarcerated, but she didn't know if he had plans for a book or any other projects that would allow him to earn a living.

The former doctor is appealing his conviction, although an appeals court has questioned whether it needs to hear the case. His attorney has argued that the court should not dismiss the appeal because it could alter his overall sentence and reduce some of the stigma his conviction has caused.

Despite being jailed, Murray hasn't been entirely silent. Audio recordings of his calls have been posted on celebrity website TMZ and the ex-doctor told the Today show that he cried tears of joy after a civil jury recently determined that the promoters of Jackson's comeback shows did not negligently hire Murray.

He did not, however, testify in the civil case or take the stand during his criminal trial.

Murray previously maintained clinics in Houston and Las Vegas and frequently complained about conditions in jail after his conviction. He was allowed to serve his entire sentence in a Los Angeles jail rather than a state prison due to a law aimed at easing overcrowding by shifting nonviolent offenders to local lockups.

"Dr. Murray has not received any special treatment in jail and in fact has many less privileges than most inmates because of his notoriety," Wass said in a statement earlier this year.

Jurors in a lawsuit filed by Jackson's mother against concert giant AEG Live LLC determined that the doctor was not unfit or incompetent to serve as Jackson's tour doctor earlier this month. The panel heard testimony about Jackson and Murray's relationship throughout the five-month trial, but the panel said it did not condone the physician's conduct.

"That doesn't mean we felt he was ethical," jury foreman Gregg Barden said of Murray after the AEG Live verdict.

No doctor or medical expert has condoned Murray's treatments of Jackson during either the ex-doctor's criminal case or the civil litigation. The former cardiologist told police he gave the superstar nightly doses of propofol to help him sleep but lacked the proper medical or monitoring equipment that's required to administer anesthesia.

Although widely used, propofol is intended only for surgical settings and experts have noted that its effects are not actually sleep.
