Investigators say the little boy found inside a suitcase in rural Indiana died from an electrolyte imbalance. The medical examiner says that the imbalance was most likely due to a “viral gastroenteritis” caused by excessive vomiting or diarrhea. State police are still working to identify the boy, believed to be about 5-year-old.

Toxicology tests came back negative and the boy had no severe injuries. Police do not believe the boy was alive when he was placed inside the suitcase. A mushroom hunter found the hardshell suitcase, which features the famous “Welcome to Las Vegas” sign. The little boy is described as just under 4 feet tall and about 40 pounds, with a slim build and a short haircut. Indiana State Police have set up a national tip line at (888) 437-6432.
