A forensic scientist testified Thursday that Jodi Arias’ DNA and Travis Alexander’s DNA was found in a blood smear on a wall in Alexander’s home.
Jodi Legg, a Forensic Scientist for the Mesa, Arizona Police Department, said she tested a swab of the blood found on Alexander’s home in June 2008, and it contained DNA profiles of both Arias and Alexander.
Legg also said she tested hairs found in Alexander’s home and those hairs matched both Arias’ and Alexander’s DNA.
Earlier Thursday, prosecutor Juan Martinez called a Mesa Police department blood splatter expert to the witness stand.
Lisa Perry testified that Alexander’s body was dragged down part of a hallway through his bedroom and into his bathroom.
Alexander’s roommates found his body in his shower in a sitting position.
Perry said the evidence found in Alexander’s house showed his blood was smeared on his bedroom and bathroom floors, which is consistent with a body being dragged from one place to another.
Perry also said this blood spot in Alexander’s bedroom shows that a large bloody surface was dragged over the carpet. She also said this spot shows that someone walked through the blood.
Perry also said blood streaks found on the floorboards of Alexander’s bedroom show that a bloody surface was dragged against the boards.
This is a bloody shoe print that could have been made by Arias.
During Perry's testimony, Arias refused to look at the photos of the blood and appeared to cry occasionally.
After testimony wrapped up Thursday, Arias' attorneys asked the judge to declare a mistrial.
They say detective Esteban Flores' testimony during a pretrial hearing in August 2009 was based on hearsay and violated her right to a fair trial, and is grounds for a mistrial.
Judge Sherry Stephens promptly denied the defense's request, saying that Flores' testimony did not violate Arias' rights.
Soon after Alexander’s body was found in June 2008, Arias told police she was not involved in Alexander's death. She later changed her story and told investigators that she witnessed two intruders break in and kill him. She eventually admitted to killing Alexander, saying it was in self-defense.
