I was totally shocked to see this list on the net..I’ll just the ones that I found totally psychotic!
Joshua Phillips
In 1998, 14-year-old Joshua Phillips bludgeoned his 8-year-old neighbor to death and hid her body beneath his bed. Seven days later, his mother noticed something leaking from beneath the bed. Joshua claimed that’s he’d accidentally hit Maddie in the eye with his baseball bat causing her to scream. In his panic he dragged her to his home where he hit her again and then stabbed her eleven times. His story failed to convince a Florida jury, who convicted him of first-degree murder. His mother is still appealing his conviction based upon the fact that he was given an adult penalty for his crime.
Willie Bosket
Willie Bosket, born on December 9, 1962, is a convicted murderer, whose crimes, committed while he was still a minor, led to a change in New York state law, so that juveniles as young as thirteen could be tried in adult court for murder and would face the same penalties. On March 19, 1978, Willie Bosket, then fifteen years old, shot dead Noel Perez on the New York subway, during an attempt to steal some money and a watch. Eight days later, Bosket shot another man, Moises Perez (no relation to his first victim) in another botched robbery attempt. Bosket was tried and convicted of the murders in the New York City Family court, where he was sentenced to five years in prison (the maximum for a minor). The short length of Bosket’s sentence caused a public outcry, and led the New York State Legislature to pass the Juvenile Offender Act of 1978. Under this act, children as young as thirteen years old could be tried in an adult court for crimes such as murder, and receive the same penalties as adults. New York was the first state to enact a law of this nature; many other legislatures have since followed suit. Bosket was eventually released from prison, but has subsequently been convicted of a number of other felonies, for which he has received a number of life sentences. He is currently in the New York prison system, in solitary confinement.
Brenda Anne Spencer - She I found was just really psychotic..seriously something wrong..just cold blooded!
On Monday, January 29, 1979, 16-year-old Brenda Ann Spencer used a rifle to wound eight children and one police officer at Cleveland Elementary School in San Diego, and to kill Principal Burton Wragg and custodian Mike Suchar. The school was across the street from her house. She used the rifle she had recently been given for Christmas by her father. When the six-hour incident ended and the pretty teenager was asked why she had committed the crime, she shrugged and replied, “I don’t like Mondays. This livens up the day.” She also said: “I had no reason for it, and it was just a lot of fun.” “It was just like shooting ducks in a pond.” and “[The children] looked like a herd of cows standing around; it was really easy pickings.” Her lack of remorse and inability to provide a serious explanation for her actions when captured inspired the song “I Don’t Like Mondays” by The Boomtown Rats, written by socialist musician Bob Geldof. Her quote “I don’t like Mondays” also appears written on a wall in the movie, The Breakfast Club.
Jon Venables and Robert Thompson
This is so sad 
Jon Venables and Robert Thompson (both 10 years old) had been stealing things all day at the shopping center — candy, a troll doll, some batteries, a can of blue paint, and other incidentals. Why did they decide to steal 2 year-old James Bulger? Was it a plot or a sudden, overwhelming compulsion? Once they had him, they didn’t know what to do with him. They could have easily discarded him, leaving him alone on the sidewalk by a shop where someone would discover the crying baby. But Jon and Robert, like children who would rather destroy their own possessions than give them to another, murdered the little boy. James’s parents would never see their baby alive again. The video cameras at the mall caught several images of James Bulger in the hands of his killers, frozen in time. He was to be taken on a long, aimless walk, cruelly tortured along the way. James was senselessly beaten to death by his ten-year-old captors, who callously abandoned him on the railroad tracks.
Mary Bell
Mary Bell was convicted of strangling a young boy, Martin Brown, on May 25, 1968, the day before her 11th birthday. She was, as far as anyone knows, alone on this occasion. On July 31, 1968, Mary and her friend (Norma Bell – no relation to Mary) took part in the death, again by strangulation, of three-year-old Brian Howe. Police reports concluded that Mary Bell had gone back after killing him to carve an “N” into his stomach with a razor, this was then changed using the same razor but with a different hand to an “M”. Mary Bell also used a pair of scissors to cut off bits of Brian Howe’s hair and part of his genitals. As the girls were so young and their testimonies contradicted each other, it has never been entirely clear precisely what happened. Martin Brown’s death was initially ruled an accident as there was no evidence of foul play. Eventually, his death was linked with Brian Howe’s killing and in August, the two girls were charged with two counts of manslaughter. Mary was released in 1980 with court ordered anonymity. In 2003, the courts awarded her and her daughter anonymity for life.
