Buffalo, N.Y. (WKBW) - The family of Amanda Wienckowski, 20, released a final report on a second autopsy done by a medical examiner they hire. Wienckowski's family has long argued that she was murdered and her body dumped in a garbage tote discovered outside a Buffalo church in January of 2009.

"She obviously didn't do this to herself and we want justice. All we want is justice;" Wienckowski's sister Danielle said.

The Erie County Medical Examiner determined Wienckowski died of an accidental overdose but preliminary results from a pathologist hired by the family, point to a different cause of death. That pathologist is Doctor Silvia Comparini and her results show a much darker cause of death.

"Doctor Comparini found signs of strangulation, defensive wounds, a sexual attack from multiple attackers," Comparini said.

Those results, once again, were found during a preliminary study. The full report will be released at 1:30 p.m. We will have all the details starting on Eyewitness News at Five.

The family has also been critical of police and their investigation into the death. They believe her murderer is a man who they said has a history of strangling woman. Buffalo police said this case remains open and they continue to investigate and follow up on all leads.
