Delaware County Sheriff's deputies investigating the death of a pregnant woman found in her car have searched a New Albany home for a second time but won't say why. Deputies are not saying if they found anything linked to the death of 23-year-old Deanna Ballman of Pataskala. Investigators have executed search warrants twice at the home three miles from where her body was found last week. Relatives says Ballman was responding to an on-line ad seeking house-cleaning help. An autopsy found no signs of trauma.Ba
