One of the fbi's foremost experts on cell phone technology takes the stand first thing tomorrow morning as the trial of Robyn Davis and Carol Sissy Saltzman continues.
Scott Davis predicts the FBI expert's testimony will help show the women killed his brother.
From the beginning the state has said the circumstantial case against Robyn Davis and Sissy Saltzman would rely heavily cell phone records. The FBI expert William Shute of Philadelphia is expected to testify how call detail records show that the women were not where they said they were during the murder of Brian Davis June 29th, 2009.
Brian's brother Scott believes the state has saved the best witness for last. "His testimony will show that these two individuals lied repeatedly to police about their whereabouts during the time of Brian's murder and will place them at the crime scene."
The defense has already attacked the methodology and expertise of the key state witness. But after a hearing, Judge David Ritchie finds the methodology is accepted and reliable. He accepts Shute as an expert saying that, in the same way medicines are often developed for one need but then useful for another, cell networks were created so we can talk but have other uses too.
Scott Davis along with other family members attending the trial have confidence in the state's case. "We want the proper individuals who are responsible for Brian's murder to be behind bars and to no longer be a threat to society. So, obviously, we don't want the wrong people put in jail for a crime that they did not commit. But we're pretty confident in the state's case and the evidence against the two."
Though the defense disputes it, a crime scene expert testified Brian Davis was probably shot with his own gun and that part of the crime scene was probably staged. Scott Davis believes the murder may have been planned a year or more before it happened. "The only thing I have figured out about those two is that they are driven by money. They are 100% driven by money."
Still defense attorneys say Davis and Saltzman are in a fight for their lives because of a crime they did not commit.
The state is expected to rest its case after the FBI's William Shute testifies.
Then the defense will have an opportunity to put on a case.
Court resumes at 8:30 in the morning.
