Davis and Saltzman trial: crime scene expert takes the stand

CALCASIEU PARISH, LA (KPLC) -

A crime scene expert is on the witness stand and has testified that Brian Davis was probably shot with his own gun and that part of the crime scene was probably staged.

George Schiro testified his evaluation of the evidence suggests that the murder scene may have been set up to look as though a tire was being changed on the Honda Accord but he says he cannot tell whether it may have been to throw off investigators or to mislead the murder victim.

Schiro also testified he believes two shots hit Brian Davis while he was bent over and then the shot that hit him in the head. Schiro says the fact that a live round was on the ground also suggests the shooter was someone not experienced with the gun. The murder weapon was never found.

He also believes the Honda Accord at the scene was probably there before heavy rain that day which means it would have been there before 3:45 p.m. 

The state is trying to show that Robyn Davis and Sissy Saltzman murdered Brian Davis and that cell phone records will show they lied about where they were the day he was killed.

At last word the defense had Schiro on cross and they were trying to show deficiencies in the handling of the crime scene by detectives. Defense attorneys suggest investigators were sloppy and contaminated the crime scene.

The jury will also hear from an FBI expert William Shute of Philadelphia who is an expert in what's called historical cell site analysis.

In an earlier hearing he explained daily they are able to use the technology of cell phone detail reports to find violent criminals, fugitives, witnesses and to rescue missing and kidnapped children.  

 


 

Prosecutors have brought in one of the FBI's foremost authorities on cell phone technology as the murder trial of Robyn Davis and Carol Sissy Saltzman continues.

The state plans to argue that cell phone records show the women lied about where they were the day Brian Davis was murdered as well as where they were the day before.

But so far, the jury has not had a chance to hear from William Shute of Philadelphia because he's been in what they call a Daubert hearing.  It's to determine whether the court will accept him as an expert. Being accepted as an expert would allow the jury to give his opinion more weight than if he were not an expert.

According to Shute, he is an expert in what's called historical cell site analysis.  He explained in the hearing that daily they use the technology to find violent criminals, fugitives, witnesses and to rescue missing and kidnapped children.

Stute testified he has taught 1500 FBI agents about the technology he used to provide information for the prosecution in this case.

However, defense attorney Maurice Tynes is attempting to attack the methodology and science that Stute uses to reach his conclusions. Stute says he's found hundreds of people using call detail records including cop killers, a man threatening suicide and missing children.
