A boy found in a suitcase in Indiana last month reportedly died of an electrolyte imbalance.
In a statement on Friday (local time), Indiana State Police Sergeant Carey Huls said the child died of an electrolyte imbalance.
"Most likely caused by gastroenteritis, which in common layman's terms would be vomiting and diarrhoea. And that resulted in dehydration," Sgt Huls said in a statement.
He also said investigators were not able to determine whether or not the boy was dead or alive when placed in the suitcase.
The child had been cleaned and clothed and placed in a small suitcase with 'Welcome to Fabulous Las Vegas Nevada' painted on the front, USA Today reported.
"He didn't put himself in that suitcase. Somebody did, somebody out there has firsthand knowledge on what happened in the situation and we need that person to come forward," Sergeant Huls said in a statement.
Huls said the boy is believed to have been around five years old but they have been unable to identify him, as no one has come forward to claim him.
"We have a child we know nothing about and nobody wants to come forward and say, 'I know this child, this is my child' or 'I know how this child got there."
USA Today reported Indiana Police Department's chaplain Todd Murphy said the boy's funeral costs have been paid for.
"He's been adopted by the county. We want to make sure he's properly cared for and properly laid to rest," Murphy said.
