CRESTON, Iowa - A family of four that was reported missing overnight has been found dead in Mexico.

Police in Creston, Iowa, say that the bodies of Kevin, Amy, Sterling, and Adrianna Sharp were discovered in a condominium in Akumal, Mexico.

The family left for a trip to Mexico on March 15 and, according to authorities, had not been heard from since.  Relatives had filed a missing persons report through the U.S. Embassy in Mexico.

Authorities say that, so far, there have been no signs of foul play and they are looking into whether the deaths could be due to food poisoning or a gas leak.

The Mexico Tourism Board said in a statement that “an investigation is currently ongoing and includes representatives of the U.S. Embassy in Mexico.”
