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 years 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.
