Authorities give more details on Iowa family's death in Mexico

According to authorities Kevin Sharp, 41, his wife Amy, 38, and their kids Sterling, 12, and Adrianna, 7, died after inhaling toxic gas. "Half my family is gone". "We don't have pilot lights because of the wind, so you light them", he said. The Sharp family rented their condo through the vacation home rental service VRBO.

They rented their vacation condo through VRBO, a website homeowners use to rent their properties to travelers.

Kids from wealthier families feel more in control of their lives, according to a Portland State University study recently released in the journal Society and Mental Health.

The condo is in the Tao complex near the beach village of Akamal, about halfway between Playa del Carmen and Tulum.

Their deaths stunned family and friends and stumped investigators, who quickly ruled out suicide or foul play based on a lack of "evidence of anything being disturbed inside the room", the attorney general's office said.

Paulina Chávez Alonzo, a spokeswoman for the Mexican Embassy in Washington, D.C., told NBC News that the government offered its "deepest condolences to the family and friends of the Sharps".

"They're just great people", said someone at the vigil.

He described a grisly scene: The family was found on Friday and had been dead for 36 to 48 hours by that time, according to autopsy results.

Immediate family members reported them as missing to local police after they did not arrive home by Friday. "We did get some closure knowing it wasn't a violent situation", she said. The family is working on getting the bodies back to USA soil for a funeral. "We haven't even thought of any lawsuit or anything like that", Hoyt added.

On Saturday, the community held a candlelight vigil at Adams County Speedway, where the Sharps were regular spectators, local NBC affiliate World Health Organization reported.

"Nothing I can say tonight can make any sense of this", the Rev. Andrew Bardole, pastor of the Corning United Methodist Church, told the crowd. "Lives that we love have been torn from us".

Kevin Sharp also was an avid stock vehicle racer, known as "the Sharpshooter" in the local racing scene, and he often competed in events in his neighboring county, friend and fellow racer Cliff Baldwin told the Des Moines Register.

"So sorry to read about the Sharp family's passing", Keselowski tweeted on Saturday.

"All the indications are that a gas leak was the cause of the death of four members of a family in Bahía Príncipe de Tulum, Quintana Roo, and installations are already being investigated to determine what happened and who is responsible", Pech said in Spanish.
