Ultimate Fighting Championship (UFC) heavyweight fighter Shane del Rosario died on Sunday evening in Newport Beach, California. It was a couple a weeks after life support was taken off him. He was 30.

On Nov. 26, 2013, del Rosario suffered a catastrophic cardiovascular attack at home. He was immediately rushed to the Hoag Memorial Hospital Prebysterian, and the doctors were able to revive him back to a stable heart rhythm and blood pressure.

According to his long time pal, former professional mixed martial artist Erik Apple, del Rosario's liver and kidney stopped functioning. He had to undergo dialysis. He was also already on life support.

Four days after his heart attack, del Rosario was taken off life support. It was initially reported that he was showing signs of improvement. He was breathing on his own. He even held and squeezed her mother's hand. He eventually gave in to the complications he has sustained from the heart attack.

He has remained in the hospital up to his death.

Del Rosario's family released a statement to The Associated Press regarding his demise. "It has been truly amazing to realize just how many lives Shane touched in such a positive way," said del Rosario's family.

UFC also released a statement following the passing of del Rosario. "The Ultimate Fighting Championship mourns the tragic loss of heavyweight competitor Shane del Rosario," said UFC in the statement. "The entire organisation sends its deepest condolences to Shane's family and friends," it said.

Del Rosario was born and raised in Orange County in California. He started his professional career in 2006. He made his debut when he competed in mixed martial arts promotion "King of the Cage." He has also competed in "EliteXC," "M-1 Global," and "Strikeforce." He has won the World Boxing Council (WBC) Muaythai World Heavyweight Championship for two consecutive years, in 2007 and 2008. He was the first American to win the title.

He was supposed to fight at UFC 168 on Dec. 28, but withdrew, even before he suffered such heart attack, because of a rib injury.
