Andre Porto said prosecutor Adam Lally that he also tested a stain on O'keefes sweatshirt on the upper front.

He said the DNA in the spot was exponentially more often to O'keefe than any other.

Porto said he also tested DNA in a stain that was taken from the back round to the right of the sweatshirt.

There were two DNA actors in this stain, probably from O'keefe and an “unknown person,” said Porto.

He also tested DNA from a rehearsal of non -tougher areas on the outside of the sweatshir.

This stain showed two DNA -actors, probably O'keefe and an “unknown person,” said Porto.

He said he tested a stain on O'keefes Sneaker, additional spots on the upper front of his sweatshirt and on the rear left cover of the shirt.

“The [DNA] Profiles that were created were not suitable for comparison for these different objects, said Porto. There were “five contributors” of the DNA that were left over the shoe, he said.

Porto said that he also tested more spots on O'keefes orange-colored T-shirt and additional spots on the sweatshirt.

He said these spots on both shirts had a DNA from a “individual participant” had exponentially more frequently from O'keefe than any other.

Andre Porto said prosecutor Adam Lally that every person with an exception to identical twins had a different DNA.

He said that DNA samples are kept in a cooling store in the laboratory, since heat can “worsen” its quality.

Porto said he analyzed DNA in the READ case from several elements. He said he compared a sample from John O'keefes DNA with the objects in question.

An article was a swab from a piece of the “right passenger” spaillight on Reads SUV.

He said the object showed three contributors, including O'keefe, their DNA on the rehearsal. It was more exponentially more likely that the DNA belonged to “and two unknown individuals” on the sample O'keefe as three unknown people, he said.

Another article was a hair from the right rear table of the SUV, he said. He said that he had not discovered a human DNA on the hair. A third object is a piece of a broken drinking glass that was recovered in the Fairview scene, he said.

Porto said the DNA of three contributors, including O'keefe, was found on the glass, and it was more exponentially more likely that the DNA came from “O'Keefe and two unknown individuals” as three unknown people.

A fourth element was a sample from a stain on the top right leg of O'keefes jeans.

Once again there were three DNA with the sample, including O'keefes and two other people, said Porto.

A fifth point was another spot on the right leg of the jeans, said Porto. Again it probably came from O'keefe and two other unknown people.

Another sample from a stain of jeans showed two participants, and it is very likely that the DNA came in this stain of O'keefe and an “unknown individual”, he said.

Porto said another stain in the jeans had O'keefes DNA and two “unknown individuals” on it.

Porto continued about the Jean spots and repeatedly points out that DNA profiles from O'keefe and “unknown” person or people came.

Andre Porto said to Lally that the crime laboratory was accredited.

He said that analysts take several steps to prevent contamination of DNA samples and that his work will be subjected to two additional reviews.

After these checks, a third administrative review is carried out to look for office in a later published report, Porto said.

He said that analysts also have to carry out regular property.

The public prosecutor Hank Brennan played an interview clip from Read, who told a reporter that when she discovered a piece of glass “on the nose” when she discovered John O'keeefe's body on the lawn in the Fairview Road, and when she removed the glass, “it only swelled blood over his face.”

The public prosecutor Adam Lally then called Andre Porto, an analyst in the state police laboratory.

Before Porto commented, judge Beverly J. Cannon advised the jury to avoid how the evidence is presented.

Porto said Lally that he was a DNA analyst in the Crime Lab.

The certificate will be resumed on Friday in the Read murder proceedings before the Supreme Court of Norfolk.

Dr. Irini Scordi-Bello, who led the autopsy over John O'keefe's body, said on Thursday that the cause of death was blunt head trauma and hypothermia.

She said she couldn't determine the type of death. Art in connection with death investigations refers to whether murder has occurred or not.

Scordi-Bello said the type of death was “circumstances, and so the circumstances may not be known to us.”
