She called the belief that scientologists don't allow medical care "garbage" and said Travolta and his wife were on a "tireless, never ending quest to get and provide him (Jett) with the absolute best care anyone could ever ask for and need."
Nestled in Florida's Marion County, north of Orlando, comparatively rural Ocala offers the Travoltas a respite from the hectic pace of Hollywood. Travolta built the family's home there and, according to a 2004 Los Angeles Times interview, keeps two planes parked on his property. Travolta is a licensed jet pilot.
The Travolta family has been living there since 2002, save brief stints in Los Angeles.
According to Ocala Mayor Randy Ewers, Travolta and Preston are active and loved members of the community.
"We called and reached out to the family," Ewers told ABCNews.com. "It's a very sad time for them. If they need anything from us we have offered that. We're just trying to help during this time and help them through this tragedy."
"They frequent the restaurants. John worked out in the local gym. They attended school here, go to the mall," he said. "Any fans that came up to them, they would spend time with them. But people let them live a normal life for the most part."
Ewers said he was unaware of specific funeral arrangements.
"I don't know of any public memorial planned," he said. "We're trying to respect their privacy as much as possible and help them through this process. They are our friends and neighbors and a fantastic family. It's very tragic."
Marion County residents have left flowers and signs outside the gated entrance to the Travolta family's Jumbolair Aviation Estates neighborhood. Neighbor Rich Koepsel told the local Ocala Star-Banner, "We consider them just normal neighbors. John and Kelly just want to be treated as another family."
He also described a close relationship between the parents and their children. "You could see the love in his parents' eyes," Koepsel told the paper. "You could look in [Jett's] eyes and feel the love there."
He described Jett as a fun-loving kid who enjoyed the outdoors, either riding around in a golf cart, pedaling his three-wheeled bicycled or going for a ride with his father in one of Travolta's antique cars or his ultra-light airplane.
In 2004, the Los Angeles Times reported that Jett and his younger sister Ella were home-schooled in Ocala to keep their education on par with the one they'd received at a Scientology-based school in Los Angeles, where they spent three months of the year.
The Times also said one of the reasons the Travoltas live in Ocala is to be close to the Flag Service Organization in Clearwater, Fla., the spiritual headquarters of Scientology.
The Travoltas will likely have a church-inspired funeral for Jett, church observers say. The Church of Scientology released a statement to ABC News detailing its views on death and funerals.
"In Scientology we believe that you have lived before and that you will live again," the statement said. "The spirit, which is you, is immortal and you are not your body. You as an individual are an immortal spiritual being and simply put, you have lived before and will live again, lifetime after lifetime. In Scientology these past existences are simply referred to as past lives.
