Paramedic/firefighter Richard Senneff testifies - Day 4 -

One of the paramedics who rushed to save Michael Jackson's life at 100 N. Carolwood Drive testified if Murray had called 911 immediately, Michael Jackson's life might have been saved.

Richard Senneff said Murray told him he called 911 the second he realized MJ was in distress, when in fact there was an approximate 20-minute delay.

According to Senneff, had Murray called earlier there was a good chance EMTs could have restarted Michael's heart.

Senneff also claimed Murray never mentioned Propofol while he was on the scene -- in fact, Senneff said, Murray patently denied MJ was on any medication whatsoever. Eventually, Murray claimed he had given MJ a sedative, Lorazepam.

Senneff said MJ was already dead when he arrived at the scene -- but they tried to revive him for 47 minutes to no avail. He said Murray refused to let them declare a time of death.

When he returned from the ambulance to pick up his equipment, Senneff said he saw Murray picking up "items" off the floor.

Murray said only that he gave Jackson the sedative lorazepam, said the singer had no medical conditions, Richard Senneff testified on Friday.

Mr Senneff, a paramedic who was the first member of his team to enter Jackson's bedroom, said Murray appeared to be frantic and was sweating profusely.

"I knew that we got there very, very quickly. It meant we'd have a good chance of restarting the heart if that was the issue," Mr Senneff said.

But Jackson's skin was cool to the touch and his eyes were open, suggesting his heart had been stopped for more than five minutes, the paramedic said.

"That did not add up to me," he said to the jury.

The paramedic said he made other observations in the 42 minutes he spent trying to revive Jackson, which did not seem consistent with the information Murray was telling him.

He told the court he saw Murray collecting items near Jackson's bed, after Jackson was taken down to the ambulance.

Murray also spent some moments alone in Jackson's bedroom before travelling with the paramedics to the hospital, he added.
