Richard Ramirez: Night Stalker

Richard Ramirez, eventually convicted of 13 counts of murder, 5 counts of attempted murder, 11 sexual assaults, and 14 burglaries, can be seen here boiling over during his trial on October 21, 1985. Ramirez’s California killing spree caught the nation’s attention with its Satanist overtones.

He is on death row.

Jeffrey Dahmer: Cannibal of Milwaukee

The mild-mannered chocolate-factory worker killed 17 men and boys between 1978 and 1991 in a gruesome spree that included necrophilia, cannibalism, and a bizarre plot to create “zombies” of his victims by drilling holes into their heads and injecting their brains with acid. He was beaten to death by a fellow inmate in 1994.

Ted Bundy: Summoning the Entity

Estimates of the number of Ted Bundy’s victims in the 1970s range from 26 to over 100, and he later claimed the part of him that he called “the entity” was obsessed with sexual violence. Often feigning helplessness with a fake cast or crutches, he targeted women in five states in the West before he was captured in Utah. The terror began again: Awaiting trial, Bundy escaped from a Glenwood Springs, Colo., jail in December 1978 and went on the lam for two months, ending his sadistic odyssey with a bloodbath in a sorority house at Florida State University and the rape and murder of a 12-year-old girl in Lake City, Fla. He was recaptured six days after his final killing, and given the electric chair in 1989.

He’s serving life without the possibility of parole in a federal supermax prison in Colorado.

Henry Lee Lucas: Serial Killer or Serial Liar?

Henry Lee Lucas confessed to killing 600 people, starting with his own mother, but later investigations proved that many of his statements were hoaxes. He was ultimately convicted of 11 homicides, but escaped execution after then-Texas Gov. George W. Bush commuted his sentence because there was doubt about Lucas’ guilt in the murder for which he received the death penalty. Lucas died in prison of heart failure in 2001.

The Beltway Sniper: Holding the D.C. Area Hostage

In October 2002, John Allen Muhammad and his 17-year-old ward, Lee Malvo, shot and killed 16 people and injured two others with a sniper rifle in several separate shootings that kept the Washington, D.C., area in a state of terror for three weeks. Muhammad (pictured) was sentenced to death.

Lee Boyd Malvo: Young Apprentice

Working under the tutelage of Muhammad, Malvo took part in the D.C. Sniper murders because he believed he and Muhammad could demand $10 million from the government — money he’d hoped would fund terrorist training camps for homeless black children. He is now serving several life sentences without the possibility of parole.

Harold Shipman: Dr. Death

Instead of working to save lives, Britain’s Dr. Harold Shipman killed at least 218 of his own patients — mostly elderly women — and possibly as many as 508 with fatal injections of drugs from 1975 to 1998.

Rader was captured in 2004 when he sent police a floppy disk from the church where he served as president of the congregation council. He is in solitary confinement in a Kansas state prison, serving 10 consecutive life terms. His earliest possible release date is 2180.
