The first characteristic a forensic handwriting expert looks for is the author's initial stroke, the point when the pen first hits the paper. What direction is the pen moving? Is it angular, is it curved? Is it perpendicular, horizontal—what is it? Cursive is much easier to identify than hand printing. In the El Segundo case, Paul was working with two samples of printing. So although it took him more time to study, he was sure the two samples—written more than forty years apart—were from the same hand.
"In all those years," Paul said later, "the suspect's handwriting had not changed one bit. It was remarkable."
Based on what Paul found, Darren Levine wanted to press charges against the suspect. Paul had called Levine and explained that he was sure they had their man.
"Darren was thrilled," Paul recalled.
Paul was no stranger to high-profile cases. He was part of a large team responsible for taking down the infamous "Billionaire Boys Club."
