Just wanted to do some research on serial killers with accomplices and found this. Also, the second link is about the psychology of male team killers. I posted a few examples of male team killers and some of female/male teams. All the information on team killing is on the links below.
"PARTNERS IN CRIME
Alton Coleman and Debra Brown
Maybe people shouldn't be surprised that a boy who had to endure the nickname "Pissy" because of a tendency to wet his pants would grow up to be one of America's most savage spree killers. And it certainly didn't help that Pissy would go to prison on a robbery charge and emerge two years later with a tendency to dress in women's clothing and a desire for rough sex. Whatever the reasons, Alton Coleman and his girlfriend Debra Denise Brown will go down in history as a short-lived U.S. version of Great Britain's multiple sex-slayers Myra Hindley and Ian Brady.
Angelo Buono and Kenneth Bianchi, the Hillside Stranglers
It takes more than a few homicides to get the attention of the people in a city the size of Los Angeles. Murders are a daily occurrence. So when three women living hi-risk lifestyles were found strangled and naked on hillsides very few people lost sleep over it. Only a couple sharp homicide detectives became nervous that this was just the beginning. Everything changed when five "nice girls" were abducted from their middle-class neighborhoods.
Two psychopathic cousins made torture into an unspeakable art form as they experimented on their young victims, giving new meaning to the concept of "Evil."
Charles Ng and Leonard Lake
Cruel, psychopathic son of wealthy Hong Kong businessman, discharged from the Marines for stealing, and his accomplice kidnapped, raped, tortured and murdered an estimated 25 captives in a fortified bunker in California -- all caught on video. When Lake killed himself with hidden cyanide tablets, Ng fled to Canada, setting the stage for one of the most expensive legal battles in U.S. history, dwarfing the O.J. Simpson trial.
The Chicago Rippers
Robin Gecht & his friends rampaged Chicago in the 1980s. They talked about how they had kidnapped women off the streets, raped them, and stabbed them with knives, razors, tin can lids, and can openers. With piano wire, they then amputated one or both breasts and masturbated onto them. Gecht's "rippers" took the flesh they had removed from their victims, cut it up, and consumed it as a form of ancient devilish communion.
The Mansonesque type of killer is rare —the person who can persuade others to kill or harm others for him. According to three confessions, Gecht was exactly that type of person. While Manson's brood was larger, the three men who followed Gecht were just as deadly, and it's quite unusual to have four people involved in such an extensive string of sexually sadistic murders.
Christopher Worrell and James Miller
Australia's first serial killer partnership was made up of a charismatic psychopath and a dependent drifter who went on a killing spree that left seven women dead.
Gary and Thaddeus Lewingdon
During the late 1970s, the city of Columbus, Ohio and outlying areas were plagued by a series of indiscriminate and brutal murders, which claimed the lives of 10 people.
The ".22-caliber killings," as they would later be dubbed by the media, began on December 10, 1977, with the murders of two women at Forkers Cafe in Newark, Ohio, some distance outside the city of Columbus. Joyce Vermilion and Karen Dodrill, had been shot multiple times as they walked out the rear door of the cafe, shortly after its closing at 2:30 a.m.
This and subsequent murders were distinguished by the amount of overkill — the bodies were literally bullet-ridden.
Finally, in 1978 suspicion focused on two truly weird middle-aged brothers, one very much under the influence of the other.
Gerald and Charlene Gallego
We have a few stock images that spring to mind when we think of serial killers. Maybe we see a Jeffrey Dahmer-type character--quietly savage, a misfit loner who practices his unspeakable avocation under society's radar. We probably do not, however, associate married couples with our notions of serial killing.
Gerald and Charlene kidnapped and killed ten people, mostly teenage girls, lured and captured in well-planned schemes, the ultimate goal of which was to provide a steady procession of disposable "love slaves." Depending on whose story you believe, Charlene Gallego was either a reluctant facilitator of, or a willing participant in her husband Gerald's tragic extended binge. After the couple's apprehension, Charlene claimed that Gerald had beaten and intimidated her into helping him, but Gerald, for his part, insisted that she had taken part in the assaults and killings. "We had this sexual fantasy see, so we just carried it out," Charlene later recounted chillingly. "I mean, like it was easy and fun and we really enjoyed it, so why shouldn't we do it?"
Henry Lee Lucas
Along with psychopath sidekick Ottis Toole, he traveled the U.S. raping, robbing, killing, and mutilating men, women & children. Originally thought to have killed 360 people, some of his confessions are now discredited. Whatever number of murders he & Toole committed, these two serial killers set a new standard in depravity.
Kevin Crump and Allan Baker
Two career criminals murdered Ian Lamb, a complete stranger for $20, a package e of cigarettes and a couple of gallons of gasoline. Then, for no other reason than that one of the men had once worked for her family as a farm hand, they kidnapped Virginia Morse, a young mother of three, from her home. Morse was raped and tortured repeatedly while Crump and Baker drove to neighboring Queensland. Next, they tied her to a tree and shot her in the eyes.
Recently, Australian courts have struggled with the constitutionality of real life imprisonment where particularly horrible killers are "never to be released."
Lawrence Bittaker and Roy Norris
He signs his prison fan mail "Pliers."
His psychiatrist saw what he was: "a highly dangerous man, with no internal controls over his impulses, a man who could kill without hesitation or remorse." When he was released from prison, Bittaker told a cellmate that someday he planned to be "bigger than Manson."
Along with prison-buddy psychopath Roy Norris, Bittaker constructed a van called the Murder Mack and collected pretty teenage girls to rape, torture and kill in the San Gabriel Mountains. In the isolated mountain areas, they went to work on their young victims with vice-grip pliers, urging them to scream into their tape recorder before they snuffed out their voices forever.
Yes, he's on death row in California a condition that stretches into decades playing cards with other serial killers, filling frivolous lawsuits against the state and selling his fingernail clippings to murder groupies.
Parole of a 'Speed Freak Killer'
They got drunk together, abused illicit drugs together, and are believed to have committed their first of possibly 20 murders together. One of them is on death row. The other on parole after serving only a few years in prison. Now, an angry public wants to know what went wrong with a system that failed to keep a suspected serial killer behind bars.
