Erotic asphyxiation - 窒息式性爱
加州圣地牙哥郡 ─週三时间，三名嫌犯于2012年，邀请一名从加州Fallbrook市的海陆特战队军人的妻子参与窒息式性爱被拒绝，将其虐待与谋杀而被判有罪。
4月13日，22岁的Brittany Killgore接受来自 Louis Ray Perez的晚餐邀请，当时她正申请与在阿富汗砲兵队服役的海军陆战队丈夫离婚，
地方报纸The San Diego Union-Tribune报导，根据圣地牙哥警察局调查员Will Altenhof的口供，在Perez 接到Killgore之后，Killgore传一封简讯给他的朋友，讯息上仅有一句话「救命」。
四天之后，Killgore被发现全身赤裸被勒死于Lake Skinner附近。
49岁的Perez、40岁的Dorothy Maraglino与28岁的Jessica Lynn Lopez，三人为SM爱好者，从事不同的性活动如綑绑、鞭打、打屁股、割人、施虐与受虐。
根据洛杉矶时报报导，Killgore 并非SM俱乐部成员。
在一封声称自杀的遗书中，被她的律师称为在三角关系中「完美奴隶」的Lopez，要负起谋杀的责任。Lopez称她用电击棒攻击Killgore，用绳子綑她的脖子，然后用枕头埋住她的脸使她窒息。
但是调查员在Perez的车中发现一包塑胶袋，里面装有电击棒与乳胶手套，车中也有Killgore的血迹。Perez的DNA留在武器上。
11月19日后宣布判决，三名嫌犯可能面对终身监禁。

Strangle With Care
David Carradine may have died attempting autoerotic asphyxiation. Is there a safe way to do that?
Kung Fu star David Carradine was found dead in a Bangkok hotel on Thursday. Police discovered him in a closet with cords tied around his neck and genitals, suggesting that he asphyxiated while engaged in a sex game. Is there a safe, proper way to perform autoerotic asphyxiation?
No. There is no doctor-approved way to strangle yourself while having sex or while masturbating. Indeed, cutting off oxygen to the brain is never a good idea. But there are ways to make this dangerous act slightly less dangerous: Do it with a trusted partner; set up a "safeword," commonly used in bondage situations, to signal your partner to let you go; don't use drugs or alcohol, which could make the strain that much riskier; and, of course, don't tie the belt or rope too tight. Some deaths by asphyxiation occur simply because the victim made escape too difficult—in one case, a man rigged it so he would have needed a bolt cutter to release his chains.
Autoerotic asphyxiation, or AEA, is typically performed in the following way: A man—the vast majority of AEAers are male—loops a belt or rope around his neck, attaches the other end to a door knob or pipe, and lowers himself into a controlled suspension. Sex or masturbation ensues. The pressure from the belt cuts off the flow of blood through the veins in his neck, causing blood to congest in the brain. Oxygen levels drop and carbon dioxide levels increase, producing lightheadedness and, for some, intensifying erotic pleasure.
When death occurs, it's usually because of pressure on a part of the neck called the carotid body, a small cluster of chemoreceptors located near the fork of the carotid artery. Pressure on the carotid body causes a discharge from the vagus nerve. This slows down the heart and can make a person pass out instantaneously. (That's why karate chops and the Vulcan nerve pinch target the vagus nerve.) Losing consciousness causes the person to go limp, which tightens the choke and decreases circulation through the neck arteries, causing asphyxiation. Rarely is there enough pressure to block the windpipe—rather, it's the lack of blood flow that causes death.
Can't you just hold your breath? Sure, but that's unlikely to have the same effect. Studies suggest that people who practice AEA do so because of the risk of flirting with death—not just because orgasms without oxygen feel good. (The bodies of AEA victims sometimes have evidence of masochism as well, like cigarette burns or mutilated genitalia.)
The first recorded case of autoerotic asphyxiation was Frantisek Kotzwara, a famous composer from Prague who died in 1791 while having sex with a prostitute. (She was tried for murder and acquitted.) Influential underground cartoonist Vaughn Bodé asphyxiated to death in 1975, according to his son. Stephen Milligan, a member of British Parliament, was found dead in his home in 1994, naked except for a garter belt and women's stockings, strangled by an electrical cord. * In 1997, a coroner called the death of INXS singer Michael Hutchence a suicide, but his girlfriend and some members of his family believed he died from AEA.
Statistics on AEA are hard to come by, since deaths by asphyxiation are often reported as suicide. But the FBI estimates that it accounts for 500 to 1,000 deaths a year. Closely related is the so-called "choking game"—the adolescent practice of strangling yourself or a friend—which caused 65 deaths in 2007.
