One Texas teenager died only a few hours after complaining of a stomach ache.
Now doctors have finally figured out what killed 17-year-old Josh Gray, reports American Web Media.
Josh was reportedly in class at Glenda Dawson High School when the pain struck, forcing him to go to the nurse's office. Two hours later, he was dead.
"He went from going to school yesterday morning -- normal day, happy -- to having a stomach ache, to within two hours not being with us anymore," recalls Josh's mother, Laurie Gray.
At first, doctors were puzzled; nobody could explain what killed Josh.
"No answers," said Laurie. "At 11:30 it's a stomachache, by three in the afternoon he's gone."
However, further investigations have since revealed Josh was suffering a ruptured artery that led to his pancreas. The pancreas ruptured shortly after the artery did, causing uncontrollable bleeding.
News of his death has left family and friends devastated.
"Josh loved everyone for who they were," Josh's friend, Austin Hurst, said, the Houston Chronicle reports. "I'm loud and obnoxious; he loved that about me. I mean, he loved all of us for exactly who we were. And that was the best part about being with Josh; you could be you."
"We love Josh," another friend, Seth Blunt, added. "We all love Josh. He's connected to us."
Now, loved ones are determined to raise awareness about the illness.
After Josh died, a friend launched a GoFundMe campaign to cover the Gray family's expenses, as well as help fund research for rare underlying disease.
"The Gray family is always the first to intercede and offer support the second someone they love is in need," the page reads. "Well, now it's our turn. While there is nothing that anyone can say or do to make this hurt any less, we would like to open this account for people to give anything they can so that this family has one less thing to think about during this time."
Within just a few days, donations quickly helped the friends surpass their initial $30,000 goal.
"So very sorry for the loss of dear Josh," wrote one donor. "We are all family in Pearland so losing him is losing one of our sweetest, kindest, caring son. The 17 on the end has meaning. That is his graduation year. He will graduate, not here on earth but in heaven."
"I am so sorry for your loss of a friend and family member," added another. "As a single mother of three, I can not contribute much, however, I hope the little bit our family can give will help."
