(Cover) - EN Showbiz - A paramedic says Dr. Conrad Murray appeared "frantic" when he arrived at Michael Jackson's home.

Emergency paramedic Richard Senneff has testified today in the ongoing trial into the singer's death.

The superstar died of acute Propofol intoxication on June 25 2009. Murray has been charged with his involuntary manslaughter, which he denies.

Senneff says he received the 911 call from Jackson's house at 12.22pm.

He arrived at the home four minutes later.

When he walked into the bedroom, the paramedic was initially unaware that the patient he was attending to was Jackson, but says he looked "underweight".

Senneff has testified that Murray "appeared frantic" when he arrived.

The paramedic asked Murray whether Jackson had any underlying medical conditions three times before the distraught doctor answered no.

He did notice that there was an IV stand and oxygen tanks around the room.

Senneff was perplexed by the doctor's reply, as an IV stand and oxygen tanks were in plain view.

The paramedic then asked Murray whether or not Jackson was on any medication. Murray said no, but did admit to giving the star Lorazepam.

Senneff claims that he and his team had a good chance of restarting Jackson's heart, if Murray had phoned emergency services earlier.

Senneff says Murray told him he had identified a pulse in Jackson, but the paramedic could not substantiate evidence of a pulse. The emergency medical team carried out CPR and ventilation on Jackson, but the ECG machine showed no heart activity.

Sennef also claimed that he saw Murray put items lying on the floor in Jackson's bedroom into a bag.

The trial continues. (C) Cover Media
