London, January 7 : Enraged Lisa Marie Presley has expressed her fury at those trying to claim that her devastated pals John Travolta  and his wife Kelly Preston suspended their son's medication following their religion's anti-medicine theories.

The couple's 16-year-old son, Jeff, who began suffering from seizures at the age of two, was found unconscious in a bathroom in the family's holiday home in the Bahamas.

The youngster had later been taken to Rand Memorial Hospital, Freeport, where he was pronounced dead on January 2, and subsequent autopsy revealed `seizure' as the cause of his death, reports Sky News.

It was alleged that Jeff's Scientology practising parents had discontinued their son's anti-seizure medicine owing to the church's alleged anti-medicine beliefs.

The celebrity couple, however, slammed the claims saying their teenager had been diagnosed with the Kawasaki disease - a rare illness that leads to inflammation of the blood vessels in young kids, with the most serious effect on the heart.

And now, the daughter of Rock n Roll King Elvis Presley, also a Scientologist, has spoken against those people trying to use the tragedy to attack the Church of Scientology.

In her MySpace blog, Presley said: "There are those certain ones that want to use this horrible tragedy as an opportunity to once again blame and/or attack Scientology."

She added: "Among most of the crazy, made-up garbage that goes around... it is not true that Scientologists don''t believe in medical care... and that may have something to do with this terrible tragedy.

"I can tell you first hand that his parents were on a tireless, never-ending quest to get and provide him with the absolute best care anyone could ever ask for and need - medically, physically, emotionally, medicinally and spiritually.

"I am not writing this to preach my beliefs, I am here to protect my friends.

"Let''s not use the tragic death of a child to facilitate your insatiable need to attack and destroy Scientology shall we?" (ANI)
