Father who strangled son, 4, released after ‘violent sleepwalking’ defense

The “violent sleepwalking” defense has worked for a U.S. man who strangled his 4-year-old and tried to kill his other two children. A jury decided unanimously that Joseph Anthony Mitchell is not guilty of murder and attempted murder after an expert witness said he was effectively unconscious at the time of his attacks four years ago. Jurors had asked Superior Court Judge James Roberson if they could consider a lesser verdict of manslaughter, but the judge said it was all or nothing: murder, or not guilty.

Mitchell’s stress and lack of sleep likely resulted in “non-REM parasomnia,” a sleep disorder whose sufferers can perform random acts unconsciously. Because of this disorder, he was incapable of exercising criminal intent.

His ex-wife, Christine Perolini, was so shocked that she hyperventilated and had to be wheeled out on a stretcher. Mitchell testified that he was in financial distress and had not been sleeping well. Prosecutors said those financial difficulties drove Mitchell to kill his son Blake and try to kill the others. Mitchell’s 13-year-old and 10-year-old children said they fought him off.
