Trial: Andrea Vogt Provides More Detail On The Bloody Footprints

1) From the prosecution testimony

Over the opposition of both defense teams, Lorenzo Rinaldi demonstrated to jurors using a precise Power Point presentation why the visible bloody footprint left on the cotton bath mat in the bathroom is attributable to Sollecito, who is on trial along with Knox for murder of her British roommate, Meredith Kercher, in November 2007….

“All the elements are compatible with Mr. Sollecito’s foot,” Rinaldi said, pointing with a red laser to a millimeter-by-millimeter analysis of Sollecito’s footprint projected onto a big-screen in the courtroom. He used similar methods to exclude that the footprint on the bath mat could possibly be Guede’s or Knox’s…

The next witness, another print expert, again confirmed Rinaldi’s testimony, that the print, which only shows the top half of the foot, matches the precise characteristics of Sollecito’s foot.

Two luminol-enhanced bare footprints were also found compatible with Knox’s right foot, Rinaldi said, one exiting her own room and another in the corridor outside Kercher’s door, facing toward the room.

All the bloody shoeprints in the room where Kercher was found were compatible with the size 11 Nike Outbreak 2 shoes believed to be Guede’s, Rinaldi said, except for one smaller, unattributed shoeprint found on the pillow that was under Kercher’s body.

Presiding Judge Giancarlo Massei asked Rinaldi what size that shoe print was, he responded “37 or 38.” He then asked what size Knox wears, and Rinaldi said according to other shoes sequestered from the crime scene, she wears a 37.

A second print expert later testified that he believed the shoeprint to be that of a woman’s size 37.5 Asics tennis shoe. No Asics tennis shoes were among the 22 pairs sequestered by police from the three’s apartments.

Rinaldi’s detailed PPT described methods of image analysis, metric and grid measurement of the ball, toe, heel and arch, as well the particular characteristics of the footprints, shoeprints as well as the actual shoes and feet of Knox, Sollecito and Guede. The three suspects gave their footprints and fingerprints at police headquarters.

2) And from the cross-examination

On cross examination, one of Knox’s defense team, Rome lawyer Carlo Dalla Vedova, questioned the certainty with which the prints could be considered compatible with Knox’s foot. He noted that a match with Sollecito and Guede’s footprints was excluded, but asked why the luminol print was not compared with the other two female roommates in the house.

Under cross, Rinaldi also confirmed that luminol, a substance used by forensic police to reveal non-visible traces of blood, also could react to other substances that contain iron, such as fruit juices, chlorophyll or rust, as well as bleach.

When asked what substance the print was made in, Rinaldi said he does only image analysis and such a determination would have to be made by a forensic biologist. That witness is scheduled to testify at the next hearing. Defense teams have all hired their own forensic experts to testify during their presentations.
