JOLIET, Ill. (AP) -- The judge at Drew Peterson's trial says he won't let prosecutors use problems with the initial investigation into the death of the former police officer's third wife to their advantage.
The question arose during testimony Tuesday as investigators took the stand to confirm they collected no physical evidence when Kathleen Savio's body was found in a bathtub in 2004.
Defense lawyers complained prosecutors were trying to suggest that if investigators had done a better job they would have found evidence proving Peterson killed Savio.
Judge Edward Burmila, however, rejected a defense request to prohibit all testimony about the shoddy investigation.
But Burmila says he won't allow prosecutors to imply that, had investigators actually looked for forensic evidence, it would have linked Peterson to Savio's murder.
