A young boy who was found dead in Indiana was discovered stuffed inside a suitcase covered with the image of the famous Las Vegas sign, authorities said.

The unidentified boy, who is believed to be between the ages of 5 and 8, was found inside the suitcase Saturday in a heavily wooded area of New Pekin, state police Sgt. Carey Huls told Fox 19 on Tuesday.

Huls said a preliminary autopsy was unable to determine a cause of death, so investigators will rely on toxicology tests to see if the child had drugs in his system when he died.

He urged anyone with information about the boy to contact authorities.

“I know it’s disturbing and shocking, but we’re hoping that with the release of the image of the suitcase, that might jog somebody’s memory,” he said.

“This obviously could be a national thing,” Huls added. “It could be a child from any location. We’re not going to preclude anybody, and we’re going to look at any information that comes in that could answer the question of the identity of this child.”

Police have asked for help from the National Center for Missing and Exploited Children’s forensics services team, according to the news outlet.

“Investigators are thankful for all the tips that are coming in but ask that the public does not send information on children already documented as missing at this time. Investigators say those cases are already being looked into,” police said, WRTV reported.
