Jan 8, 2010— -- Prosecutors are prepared to indict Michael Jackson's doctor for involuntary manslaughter in the death of the pop star, ABC News has learned.
Dr. Conrad Murray, a Las Vegas-based cardiologist who was with Jackson when the pop singer died after receiving a lethal cocktail of painkillers and anesthetics June 25, has long been the focus of a homicide investigation.
Officially, the Los Angeles District Attorney's office said that no final decisions had been made in the Jackson case.
"We don't have a case. It hasn't been presented. Don't know when we'll get it," Jane Robison, a spokeswoman for the DA's office, told ABC News.
Murray's lawyer said his client had not yet been made aware of any indictment.
"We have refused to comment on stories involving unnamed sources and will continue to do so. However, we can confirm that we have not received notice of an impaneled grand jury and Dr. Murray has not been invited to testify," said Ed Chernoff in a statement.
According to police reports, Murray found Jackson dead in the singer's Los Angeles rental home before administering cardiopulmonary resuscitation and calling 911.
In October, the coroner's office released a statement saying Jackson had died from an overdose of the hospital-grade anesthetic propofol.
The coroner also cited the powerful sedative benzodiazepine as contributing to the singer's death. A toxicology screen and search of Jackson's home found several other drugs in the singer's body and bedroom.
After the investigation, a slew of liens and lawsuits against Murray was discovered. In the last three years, Murray has faced lawsuits for unpaid business bills totaling over $700,000, including rent on his medical offices.
