[video] Paramedic: Jackson was dead on arrival

The paramedic who rushed to assist Michael Jackson testified Friday that the pop star had flatlined by the time emergency help arrived. Firefighter paramedic Richard Senneff said he also saw Dr. Conrad Murray stashing several items into a plastic bag. Senneff responded to Jackson's residence after receiving a call of "patient not breathing." Senneff said that as he sized up the scene, he saw what he believed to be an underweight man hooked up to an IV. When he learned there was a doctor in the room, he asked whether there were Do Not Resuscitate orders in place. In other words, his initial impression was that this was a sick man. But he says he had to ask Murray three times what the patient's underlying condition was before Murray responded, "Nothing." Senneff's take of the situation? "It didn't add up." He testified that Dr. Murray told him that the only drug he had administered to Jackson was lorazepam to help him sleep and there was no mention of propofol. Jackson did not respond to any resuscitative efforts. The paramedics were ready to stop resuscitation because they believed he was dead, but Murray insisted he felt a right femoral pulse. Senneff says he checked again and still found no pulse. As paramedics were taking Jackson out the bedroom on a gurney, Senneff says he saw Dr. Murray picking up items in the bedroom and putting them in a bag. Senneff said Dr. Murray rode with him in the ambulance on the way to hospital and that Jackson showed no signs of heart activity during the transport to the UCLA Medical Center. In fact, Senneff testified he did not see any signs of life from Jackson during the entire 42 minutes he was assisting Jackson.
