With access to exclusive and never-before-seen interviews, insights from law enforcement and leading experts in profiling, criminology, and psychology, conversations with survivors, new archive and more, viewers hear first-hand how the actions of these cold-blooded killers unfolded, leaving behind hundreds of innocent victims and their grieving families.
Charles MansonCharles Manson was born in 1934 to a troubled family. At a young age, he began stealing, ending up in reformatories then jail and prisons. In his 30s he began to attract a following of waif-like women who were in his thrall. Then in 1969 he had his group invade the home of pregnant actress Sharon Tate, killing her, her unborn baby and four friends. Later they killed Rosemary LaBianca, scrawling "Death to Pigs" in her blood around the house. He received the death penalty, later commuted to a life term in Corcoran Prison in California.
Miyazaki TsutomuBorn in 1962 into a wealthy Japanese family, Miyazaki Tsutomu had a congenital hand defect, such that he was unable to hold his hands palm-up. He was ostracized as a child and began to lurk around young girls, stalking them. In 1989, he kidnapped and murdered four young girls, mutilated their bodies and drank the blood of one victim. When his crimes were discovered, his father committed suicide out of shame. Miyazaki coldly regarded that as "just punishment" for not raising him correctly. He was executed in Tokyo in 2008.
Warm blooded animals in cold climates are pretty large, even the smallest Antarctic birds are on the large side and the smallest Antarctic penguin, the Rockhopper is a fairly hefty 2.5kg (5.5lb). The Adelie and Emperor penguins of the deep south are larger still. Adult weights are 5kg (11lb) for the Adelie and 30kg (66lb) for the Emperor - a similar size to an overweight 10 year old child, but with a man-sized chest measurement.
This fat layer is the best form of internal insulation yet devised by mother nature - and therefore the best way to keep warm in water. It keeps all warm-blooded cold water animals operational down to minus 1.9°C (25.8°F). Why this temperature? - because that's when sea-water freezes, you can't get sea water colder than that without it being solid. A penguin can have up to 30% of its body weight as blubber (fat).
Penguins have a heat-exchange blood-flow to these regions called "Rete Mirabile". The warm blood entering the feet flows past cold blood leaving so warming it up in the process and cooling the blood entering at the same time, the same sort of thing happens in the flippers. Blood in the feet and flippers is kept significantly colder than in the rest of the body much of the time. By the time the blood re-enters the rest of the body it has been warmed up and so doesn't have so great an effect in cooling the core body temperature.
Penguins feet are never allowed to get below freezing point, blood flow is finely adjusted so that they are kept just above. When it gets very cold, the feet are covered by the feathers and fat layer of the body so they are not exposed to icy winds. So while a man standing barefoot on ice would quickly get frostbitten, penguins can do so all their lives with no damage at all.
This is what penguins do except they don't stand on tip-toes when it's really cold, they rock backwards on their heels, holding their toes up. They stop themselves from falling over backwards by using their stiff tail feathers that have no blood flow and so lose no heat as the third element of a tripod.
3/ A fat layer improves insulation in cold water, up to 30% of a penguins body mass can be blubber, though this is not sufficient on its own to keep the body temperature stable at sea indefinitely in the coldest temperatures. Penguins must remain active while in water to generate body heat. Unlike other warm blooded Antarctic marine animals such as seals and whales, penguins are still relatively small, so the "be big" strategy is not taken as far as needed to remain warm even at rest in the sea as in seals and whales.
A cold-blooded murderer takes the life of local football hero TK Kelly. The high school standout had carried the dreams of his small California city on his shoulders, but for someone close to TK, jealousy of the star was motivation enough to kill. 1e1e36bf2d
