After a day of fishing in a small quiet village in Switzerland, a teenage boy did not return

home as planned.

The investigation revealed some important microscopic evidence in the water near where he was

last seen.

It was the only forensic evidence detected's head.

Late in the afternoon of August 4, 1993, in the small Swiss village of Neuparides, 13-year-old

Dario Chicollecchia left his home to go fishing in a nearby creek.

His night fell on the town.

Dario had not returned home, and his mother called the police to report her son missing.

When we found the bike and his clothing, we concluded that he had last been fishing there.

Where and with whom he could have left the place, we had no idea.

Two days passed, and the search intensified with more than a hundred policemen, but trolling

the area with search dogs.

A missing person poster aired on local television and newspapers asked, where is Dario?

As time passed, people feared the worst.

To us, there were clear indications that a crime had taken place because of the objects

found, his bike and his trunks.

Search teams meticulously combed the field next to the creek where Dario's swim trunks

and fishing pole had been found.

Farther downstream, police found Dario's t-shirt on the bank.

A dam was placed in the creek in order to search the muddy bottom for evidence.

Many items were discovered, but nothing that could be linked to the missing boy.
