Experts find no DNA match in Porco blood samples

Friday, two New York State forensic pathologists took the stand and testified about DNA and blood samples that were taken from the Porco home. They tested them and found no absolute matches with Christopher Porco.

"There's absolutely no forensic evidence between Christopher and the commission of the crime, and I think that's the biggest thing that happened today," Defense Attorney Terence Kindlon said.

The scientists found blood in Chris Porco's jeep and on one of his t-shirts. But, DNA testing proved the blood was his own.

"Out of the bloodbath you would have expected blood would get into his jeep, and it would be filled with evidence. It would be filled with DNA, blood…and it was clean as a whistle," Kindlon said.

"There's no unaccounted for DNA. There's no mystery DNA. You know Christopher Porco was very careful in what he did and covering his tracks," Chief Assistant District Attorney Michael McDermott said.

The prosecution also called the experts to the stand to show they did, in fact, do a complete and thorough investigation of the case despite what the defense has been saying. Later in the afternoon, they called Chris Porco's uncle to the stand.

"The body of his parents would have been discovered, and he knows right then and there he has to start accounting for where he was, and he's with somebody he's known all his life. And he gives him the same tall tale that he's given everybody else which simply wasn't true," McDermott said.

The DNA expert also testified that the DNA on the toll ticket could only be identified as male, but the prosecution said that they'll call another expert Monday that will prove that the DNA on the toll ticket was actually Christopher Porco's.
