Conrad Murray Trial: Scene in Michael Jackson's Room 'Did Not Add Up,' Paramedic Says

First responders testify about what they found in Dr. Conrad Murray trial.

Oct. 1, 2011 — -- The first paramedics to arrive at Michael Jackson's Holmby Hills mansion the day he died found the singer lifeless, Dr. Conrad Murray frantic, and a situation that one said "did not add up."

Paramedics who testified Friday at the trial of Murray said they discovered the pop superstar on his bedroom floor, wearing only a surgical cap and his pajama top, with his ribs visible. His skin was cold and turning blue.

"His eyes were fixed and dilated," paramedic Martin Blount said.

When asked if he had an opinion as to whether Jackson was alive, Blount responded, "Um, felt he was dead, ma'am."

Paramedic Richard Senneff testified that he saw medicine bottles on Jackson's nightstand, but that a frantic Murray claimed he was treating Jackson only for dehydration and exhaustion with a sedative, Lorazepam, for sleep.

"That did not add up to me," Senneff said.

When asked why, Senneff said, "Doctor's in the house; uh, IV pole -- IV hooked up to the patient. It didn't seem normal."

Senneff said Murray never mentioned having administered the surgical anesthetic propofol to Jackson.

For 42 minutes, paramedics used CPR and drugs to try to restart Jackson's heart and a resuscitator known as an ambu bag.

"The [EKG] monitor -- the heart monitor was a clean flatline," said Senneff.

Senneff testified that before they left the mansion, Murray was spotted scooping up items from the bedroom.

Even though UCLA Medical Center suggests that paramedics declared Jackson dead in his bedroom, Murray pushed them to keep trying to resuscitate him in the ambulance ride to the hospital.

At the hospital, Murray said nothing about propofol to Dr. Richelle Cooper, who testified that she saw no signs of life in Jackson either.

"I confirmed there was no pulse," Cooper said in court.

Murray is charged with involuntary manslaughter and could face four years in prison if convicted.

Former prosecutor and defense attorney Susan Filan told ABC News that the prosecutors are building a "very strong" case against Murray.

"What they have to show is that Murray's conduct was negligent and reckless, that it was involuntary manslaughter. They don't have to show that he killed him on purpose," Filan said.

Filan said the paramedics' testimony supports the theory that Murray was covering up something.

"[The defense team] is going to say that this was an accident, and that Michael Jackson administered the fatal dose of propofol to himself. But there are going to be things that are going to negate that. One, he had what's called a condom catheter, which would indicate that he wasn't able to get up and move around the room once he was under sedation," said Filan.

"The whole question of sedating somebody at home with propofol without the proper care -- and Murray walked out of the room after he gave that last dose," Filan added. "There are just too many things wrong with this and it just doesn't add up. I think he's in trouble."
