Iowa trucker charged in 1990s cold-case murders of 3 women

IOWA CITY, Iowa (WHO/AP) -- Investigators on Wednesday arrested a long-haul trucker from Iowa who they say is linked by DNA evidence to the killings of three women whose bodies were dumped in Wyoming and Tennessee in the early 1990s.

Police arrested Clark Perry Baldwin, 58, at his home in Waterloo, Iowa, on murder charges filed in Wyoming and Tennessee in the deaths of the women, including two who were pregnant. Investigators said they were looking into whether Baldwin could be responsible for other unsolved slayings.

Baldwin was arrested after investigators used semen and other material recovered from the victims to develop DNA profiles of their perpetrators, according to court documents in Wyoming. Last year, they learned that the same profile matched all three cases.

Investigators zeroed in on Baldwin after finding DNA in commercial genealogy databases of someone related to the suspect's profile, court documents say. Last month in Waterloo, the FBI secretly collected DNA from Baldwin's trash and a shopping cart he used at Walmart and it matched the profile.

In 1997, Secret Service agents raided Baldwin's apartment in Springfield, Missouri, after learning he was making counterfeit U.S. currency on a personal computer. He and two female associates were indicted on counterfeiting charges. Baldwin was sentenced to 18 months in prison and released in 1999.
