Criminal Minds

Reid: Derrick Todd Lee used the tape of a baby crying to get women to open their doors in Baton Rouge. Although the crying-baby ruse is an urban legend, Derrick Todd Lee, a career criminal, was convicted of the rape and murder of several women in the Baton Rouge, Louisiana, area in the late 1990s and early 2000s. He was sentenced to death by lethal injection in 2004.
Supervisor: …he's kinda the on-site Kevorkian. Known by the nickname "Dr. Death," Dr. Jack Kevorkian claims to have assisted more than 130 people, some of whom were terminally ill, to commit suicide. Kevorkian was tried and convicted of second-degree murder of Thomas Youk in 1999, after which he served eight of his 15-year sentence.
Reid: It's not uncommon for duos to be related. The Hillside Stranglers were cousins, the Carr brothers perpetrated the Wichita Massacre. Reginald and Jonathan Carr, two brothers with criminal records, went on a killing spree in the city of Wichita, Kansas in the winter of 2000. They started with armed robbery and quickly advanced to murder. Two out of seven victims survived. The case was dubbed The Wichita Massacre, and is also known as The Wichita Horror. Both brothers were sentenced to death in 2002, with additional life sentences for other crimes. Angelo Buono and Kenneth Bianchi, two psychopathic cousins, were collectively named the Hillside Strangler. The crimes took place in late 1977 to early 1978 in the hills above Los Angeles leaving at least ten dead. They used fake police badges to lure their female victims into their car, after which they took them home and abused, tortured and strangled them. Bianchi is serving a life sentence in Washington. Buono died of a heart attack in Calipatria State Prison in 2002 where he was serving a life sentence.
Morgan: Think of the family annihilators John List and Mark Barton.

Mark Barton was a spree killer from Stockbridge, Georgia, who in 1999 shot and killed nine people and injured 13 more. At his home, police found that Barton's second wife and two children had been murdered by hammer blows a few days before. The children had then been placed in bed, as if sleeping. He said he forced himself to do it to keep them from suffering so much later. Barton committed suicide on the day of the killing spree when he was spotted by the police. John List murdered his mother, his wife and three children in Westfield, New Jersey, in 1971. He disappeared and lived under a pseudonym until he was apprehended in 1989. List wrote a letter to his pastor explaining that he was sending his family directly to heaven by killing them before they could renounce their religion. He was sentenced to five life terms in prison.

Prentiss: PTA moms, gray flannel dads - these guys are killing the Cleavers.

The team compares the murdered family with the Cleavers, the idealized suburban family from the 1957-63 series Leave It To Beaver. This was a program about a happy American family, but Reid thinks the name Cleaver has "violent implications" and wonders how the show's writers really felt about suburbia.
