3:45 p.m. Source of bruises? 'I don't know'

Dr. Larry Blum testified he doesn’t know for sure whether or not the three bruises on Kathleen Savio’s hip area came from injuries unrelated to her death in the bathtub.

"Dr Blum you don’t know if she banged into a drawer do you?" asked defense attorney Ralph Mecyzk.

"I do not," Blum said.

"You don’t know if (the bruising came) during the course of having…at some point having aggressive or rough sexual intercourse do you?" Mecyzk asked, referring to Savio having sex with her boyfriend the Friday night before she was found dead.

"I suppose that’s within the realm of possibility – I don’t know, let’s put it that way," Blum replied.


3:30 p.m. Defense presses doctor on lack of DNA

After sparring with Dr. Larry Blum over his interpretation of slides that he testified showed deep bruising on Kathleen Savio’s left hip area, defense attorney Ralph Mecyzk questioned him about what was found under Savio’s fingernails.

Prosecutors have alleged Drew Peterson placed Savio in a choke hold until she was unconscious and then drowned her in her bathtub.

Meczyk questioned Blum about why no evidence supporting that theory was found under Savio’s fingernails.

"You would expect that during a struggle, there would be…DNA or tissue underneath the fingernails, correct?" he asked

"Yes if the victim scratched the assailant, there may be — correct," Blum replied.

"There was no male DNA identified is that correct?" Meczyk asked.

"That’s correct," Blum replied.
