I only have a bit of publicly-released info on each case. But it seems to be a fairly common phenomenom. Other examples:
4-24-98
Andrew Wurst 14, Edinborough, PA, Parker Middle School(at off-campus school dance); 1 dead, 3 wounded
.....As the police got to know more about Andrew's friends, they began to wonder if one of them was a '
puppet master' who may have manipulated Andrew into using the gun or at least encouraged him."
--"...Andrew had mentioned in a letter to a friend that '
the voices are coming again.' " "Andrew thinks he is real, but everyone else is unreal. Other people are programmed to act and say what
the government, mad scientists, or a psycho wants them to say." [interesting juxtaposition of those last three groups!]
--Andrew told his girlfriend "We are all in reality in hospital beds being monitored and programmed by these mad scientists, and this world is not real for them. The scientists watch over us to see what we're doing." [uh oh, he wasn't supposed to remember this part!]
5-20-99
T.J. Solomon, 15, Conyers, GA, Heritage High, 6 wounded--Witnesses described the shooter as initially "calm, sedate, vacant, and robotic."
--Dr. Eddy Regnier, a teacher of psychiatry at Harvard University and who was hired by defense attorneys to examine T.J. said that T.J. had suicidal thoughts and
believed to hear voices giving him commands. “He heard voices telling him to do strange things, but they were robotic voices, not human voices”

St.Neots, Cambridgeshire, England
http://www.dailymail.co.uk/pages/live/a ... _id=511092 A schoolgirl accused of filming herself attempting to murder her parents claimed
a voice inside her head insisted that she kill them.The 15-year-old, who videoed herself putting a noose around her mother's neck and trying to stab her father with scissors, said she never intended to hurt her parents.
She told a jury she pretended to carry out the voice's instructions in the hope it would go away for long enough for her to get psychiatric help. She described how she had asked for counselling at school when she began hearing the voice - which made derogatory remarks and said she was worthless - in Year 8.... At first, she said, she managed to make it go away but she gradually had to take more extreme measures - hitting, slapping or taking a blade to herself - to make it disappear.
When she went upstairs, the voice started to talk to her, jabbering "
Do it. Do it", she said.
"It gave me an image of my mother with a noose around her neck, my father with a knife in his chest," she said. "They were dead."
-- The acts were a 'pretence' designed to
placate a voice in the girl's head and get psychiatric help, Mr Malcolm told the jury.
..in addition to making the video, she also typed out on her computer her plan of how she would attack her parents as her sister looked on. It included a passage "
Go in, nothing strange, set up a camera, loop mums head and pull. Dad will come to help her, I will stab."
