You may have heard the good news that DNA testing has uncovered a serial killer who murdered a dozen people in South Los Angeles. Now the bad: Another man, "a barely literate part-time janitor described by a psychiatrist as having the mental capacity of an 8-year-old," spent 9 years behind bars (note: was previously "11 years") after being wrongfully convicted in the slayings of three of the victims. There were no witnesses, no corroborating evidence, just "the inconsistent statements of a man who was found to have an IQ of 60 to 73 and cannot read words longer than four letters." Who waved his rights to a lawyer, was badgered into a "confession," part of whch was not taped. Whole ugly story here (reg. required).
