Another suspect in Chicago was been charged with hunting and killing drug-addicted prostitutes. The new suspect, Geoffrey Griffin, 30, was charged with strangling or beating to death seven women during the summer of 2000. The charges came 17 months after he was initially jailed on suspicion of committing the slayings. Griffin was charged two summers ago with first-degree murder in the killing of Angela Jones, a 32-year-old mother of seven, after he gave police a videotaped confession. Jones, whose body was discovered May 12, 2000, was the first of seven black, drug-addicted prostitutes who were found dead in abandoned buildings. At that time, Griffin denied involvement in the other women's deaths, but police said he was responsible for the slayings even though there was no solid evidence. DNA test results later connected Griffin to each of the seven killings, said Lt. Joseph Murphy.
