Pedro Lopez is a Colombian serial killer. He was sentenced in 1980 in Ecuador for killing 110 girls, but who claims to have raped and killed more than 300 girls across Colombia, Peru, Ecuador, and potentially other countries. That would make him the second most prolific known serial killer in history.
He was released in 1994, rearrested an hour later as an illegal immigrant and handed over to Colombian authorities, who charged him with a 20-year-old murder. Lopez was released by Colombia in 1998 on $50 bail and some conditions. He absconded. At present, Lopez is wanted in connection to a 2002 murder, and his whereabouts are unknown.
In 1901 Colombia minted special coins for use in leper colonies. Following the first leprosy congress in Berlin in 1897, the nation minted coins in five values for use in three colonies. The point was to keep leprosy from being spread, by preventing money touched by lepers from getting circulated throughout the population.
The Philippines followed suit in 1913, followed by Japan and Malaysia. The United States produced special coins for a colony in the Panama Canal Zone. The coins were produced to protect healthy people, but in 1938 Gordon Alexander Ryrie, director of Malaysia’s Sungei Buloh Settlement, proved that the disease can’t spread by such casual contact. His colony burned the notes it had printed.
Usually, when we think of gold, we think of a warm yellow color. But the Nahuange, who lived in northern Colombia during the first millenium CE, intentionally treated gold jewelry so that it looked pinkish orange. A recent study analyzed 44 Nahuange artifacts from the Museum of Gold in Colombia, and found that they were made from tumbaga, a gold alloy which contains a substantial percentage of copper. They were also all “depletion gilded” which means copper was removed from the surface through hammering, a heating and cooling process, or both. The result was a golden shine on the outside which hid the metal’s true high-copper content.
That gilding was later removed, on purpose, to bring the copper’s pinkish tones out. So initially, the jewelry makers desired golden objects, but at some later point, it was preferable to have pinkish-orange jewelry.
