Disappearance of Juan Pedro Martínez

A 10-year-old boy named Juan Pedro Martinez disappeared in Spain in 1986, while on "vacation" with his mother and father. His dad, who was a truck driver, was delivering a load of 20,000 liters of pure sulfuric acid. Everything seemed normal until the family reached the Somosierra mountain pass when his father started driving erratically, crashing into several cars and then overturned his truck. Sulfuric acid began pouring out of the tanker, causing a cloud of noxious gas to rise near the crash site. Both his parents were killed. Juan however, was never found at the accident site. Some believed that Juan was completely dissolved by the sulfuric acid. However, chemists maintain that there is no way that this happened. The acid could not have dissolved his body that quickly and leave no trace.
