He deposited two checks totaling over $200,000 from Erie's sister company Garment Conveyor Systems, as requested by corporate counsel to keep monies safe from Dosso and Gonsalves.
But, almost three years later, law enforcement agents found his fingerprint on a parking garage receipt at Orlando International Airport dated 3:49 p.m. on Dec. 3, about two hours before the slayings occurred.
In a court hearing in September 2013, Prosecutors admitted to withholding from defense counsel the testimony of the only eyewitness to the murder scene, John Purvis.
However, the prosecutors convinced the 12-member trial jury that Serrano had flown by airliner to Florida under assumed names to commit the premeditated murders.
Then he had quickly flown back to Atlanta from a different major airport to attempt to establish an alibi by appearing on the security video cameras of his hotel.
Although Bartow is midway between the major airports in Tampa and Orlando, evidence was not shown to prove this trip positively and that murders could be possible during rush hour traffic.
Serrano was kidnapped in Ecuador by Florida-hired off-duty police officers and then, according to the Ecuadorian government and the Inter-American Commission on Human Rights (a division of the Organization of American States), illegally deported back to Florida for his murder trial.
Judge Roberts, unaware that an extradition process was started and thwarted by state attorney Wallace, denied the defense motion, finding no cause to dismiss the case.
Ecuadorian officials, seeking his return to that country, claimed Serrano had been beaten and kept in a dog kennel at the airport in Quito after his arrest in Ecuador.
Judge Roberts denied a defense motion for a change of venue, although one of the victims, Diane Dosso Patisso, was an Assistant State Attorney for Polk County.
Serrano was on death row at a male-only maximum security prison facility at the Union Correctional Institution in Raiford, Florida.
