'I'm good, let's roll': Last words of Ohio murderer on death row I'm good. Let's roll," Brett Hartman, 38, said before he was executed by lethal injection, according to Ohio Department of Corrections spokesman Mike Davis. Mr Davis said Hartman's sister, friend and lawyer, along with a friend of the victim, were present for the execution. Hartman, who spent 15 years on death row, was convicted for the 1997 murder of a 46-year-old woman - identified as Winda Snipes - whom he had met earlier in the year at a bar in Akron. The pair subsequently had sex several times. According to court documents, one night in September, Hartman tied the victim down to the bed, stabbed her 138 times, slit her throat and cut off her hands, which were never found. Hartman was convicted of aggravated murder, kidnapping and tampering with evidence, but insisted he was innocent, saying he had discovered the woman's body, "freaked out" and tried to remove evidence of his presence in her apartment. All of his appeals, which centred around DNA evidence, were rejected, including one that went to the Supreme Court.
