An Iowa family that had been reported missing has tragically been found dead inside a Mexican condominium.
A statement issued by the Quintana Roo prosecutor's office on Twitter said the four family members - Kevin Sharp, 41, his wife Amy Sharp, 38, and their children Sterling, 12, and Adrianna, 7 - died from "asphyxiation from inhaling toxic gases".
Mexican investigators are now looking into the condo's gas system to determine how the family was exposed to the toxic gas. The Sharp family appeared to be dead for 36 to 48 hours when they were discovered, the office said.
The family was reportedly staying in a rental house they found through a vacation rental company.
Amy's sister, Renee Hoyt, told Creston News Advertiser that the couple flew to Cancun, where they planned to rent a vehicle and drive to Tulum.

The State Department is now advising "increased caution" for Americans travelling to Mexico, with the area the Sharp family were staying seeing an experience in homicides this year. They were found last night in their condo deceased.
The Sharp family was scheduled to depart the Cancun airport at 2:45 p.m. Wednesday to return to St. Louis on a non-stop flight. The last contact the family had with the Sharps was a picture the son posted on Snapchat of his feet by the water that day, Weland said.
"Everything they did, they did as a family", Harris said.
The Sharps' family members made a decision to wait for the last flight from Cancun to St. Louis to arrive on Thursday in case the Sharps had just planned to stay an extra day, Weland told ABC News. "Most people don't appreciate the fact that when you come to this racetrack, this is a family", a friend of the Sharp family said.
