ce that the four might be innocent. The state's ease fell apart in 1996, of ter DNA evidence showed that none of the so-called Ford Heights Four could have raped the woman victim. It was only one case, but it had a searing effect in Illinois for this reason: three other men confessed to the crime and were convicted of it. The original four were unquestionably innocent--and two ofthem had nearly been executed. By then other Illinois capital cases were falling apart. Some of the key legwork in unraveling bum convictions came from Northwestern University journalism students. Late in 1998 their school hosted a conference on wrongful convictions. The event produced a stunning photo op: 30 people who'd been freed from death rows across the country, all gathered on one Chicago stage. But it was another Illinois case, early in 1999, that really began to tip public opinion. A new crop of Northwestern students helped prove the innocence of Anthony Porter, who at one point had been just two days shy of lethal injection for a pair of 1982 murders. Once again, the issue in Illinois wasn't the morality of death sentences, but the dangerously sloppy way in which they were handed out. Once again a confession from another man helped erase doubt that the man convicted of the crime, who has an IQ of 51, had committed it. By last fall the list of men freed from death row in Illinois had grown to 11. That's when the Chicago Tribune published a lavishly researched series explaining why so many capital cases were suspect. The Tribune's digging found that almost half of the 285 death-penalty convictions in Illinois involved one of four shaky components: defense attorneys who were later suspended or disbarred, jailhouse snitches eager to shorten their own sentences, questionable "hair analysis" evidence or black defendants convicted by all-white juries. What's more, in the weeks after those stories appeared, two more men were freed from death row. That pushed t...
