There are no new answers for the family of Teleka Patrick, after a second autopsy was performed at the family's request.
Private investigators say the second autopsy was conducted by the coroner's office in Marion County and matched the findings of the coroner in Porter County.
There were no signs of trauma or foul play and the initial cause of death appears to be drowning.
Toxicology results are still pending.
Patrick's body was pulled from Lake Charles last Sunday.
The doctor's car was abandoned nearby on Dec. 5, along Interstate 94.
