Microscope to compare the similarities. they found paint on both the t-shirt and the bathrobe with the same chemical makeup. what i believe happened now, there is an evidence transfer from the blue t-shirt deposited on to the pink bathrobe. this proved that sarah had worn the robe over the top of her t-shirt. finally, investigators analyzed the gloves found in the garbage. when you handle an item and you leave behind the oils and residues from your skin, that contains skin cells. and we are oftentimes able to get dna from those samples. scientists swabbed the inside of the gloves and found dna from only one person. sarah was the source of the dna found on the latex glove. all the clothing found in the garbage can was then checked for gunshot residue, a gas created
Inconsistency, not evidence of murder. this case was going to be very difficult to prove to a jury. there was not one single piece of evidence necessarily that totally committed sarah to this crime. and so we just had to build it piece by piece. the piece they thought might prove most significant was the t-shirt and pajama bottoms sarah was wearing on the morning of the murders. police, when they first approached her, saw no blood on her clothing. there was none there, because we luminoled every inch, top to bottom. nothing. analysts now turned to the pink bathrobe found in the garbage the morning of the murders. family members said the robe belonged to sarah. as rod engler examined it with a proscope, a high-powered microscope capable of 400 times magnification, he was shocked to discover no blood spatter on the

Robe backwards, but investigators needed to prove that sarah wore the robe on the morning of the murders. to do that, they had to analyze the shirt she had on that day. sarah johnson had a blue cotton t-shirt with green paint smeared on to it. so, therefore, i m thinking, well, let s examine the blue shirt now and see if any of that cotton fiber could have transferred with the green paint on to the bathrobe. scientists took samples from the t-shirt and fibers from inside the bathrobe. they used a scanning electron microscope to compare the similarities. they found paint on both the t-shirt and the bathrobe with the same chemical makeup. what i believe happened now, there is an evidence transfer from the blue t-shirt deposited on to the pink bathrobe. this proved that sarah had worn the robe over the top of her t-shirt. finally, investigators analyzed the gloves found in the garbage.
