Prosecutors refused to reopen the 44-year-old investigation into the killing of Dr. Sam Sheppard's wife, calling new DNA tests presented by his defenders "unreliable."
County prosecutor Stephanie Tubbs Jones said Thursday she had not seen the test results, which a lawyer for Sheppard's son released earlier in the day.But prosecutors said the crime scene was trampled, and Jones said the tests were run on contaminated samples that would be useless in court.
"It's unreliable, it's untimely, it's contaminated, it's tainted," Jones said.
