Police in Indiana, USA are awash in mystery following a gruesome discovery made last month.

On April 16, a citizen who was looking for mushrooms discovered a suitcase in the middle of the forest.

However, the suitcase contained the body of a child, whose identity remains unknown, even a month after its discovery. It would be a young boy aged between 5 and 8 years old. He is about 1.20 meters (4 feet) tall. The child is thin and has short hair.

The young boy is believed to have died about a week before his body was discovered.

However, an autopsy last month could not establish the cause of his death. The police hope that the toxicological analysis will be able to enlighten them.

Over the past month, the police have received several hundred calls from citizens who wanted to provide information to investigators. So far, the authorities do not know the exact name and age of the child.

The police do not exclude that the boy could come from another country.
