The driver of Antonio Trangia appeared before the Senate Committee on Public Order and Dangerous Drugs hearing on Monday.
Romeo Laboga told lawmakers that he did not take University of Santo Tomas (UST) law student Horacio "Atio" Castillo III to the Chinese General Hospital in Manila last September 17.
He said at about 5 am on that day, he was in a tile supply shop of his employer Antonio Trangia along MacArthur Highway in Meycauayan, Bulacan.
He also denied driving a Mitsubishi Strada red pickup.
He said he did not know anything about the vehicle.
He said Pajero was the vehicle he was driving for his employer.
He also claimed to be with Antonio Trangia on Septemner 17.
Laboga's testimony contradicts the statement of Aegis Juris fraternity member John Paul Solano, one of the primary suspects in Castillo's fatal hazing.
Solano previously claimed he brought the dying body of Castillo to the hospital.
He was supposedly accompanied by fellow fraternity member Arvin Balag to the hospital and that it was Laboga who drove the red pickup.
Laboga's employer Antonio is the father of fraternity member Ralph Trangia, also a primary suspect.
Senator Grace Poe says, the conflicting testimonies may be because of reports that it was actually Balag's driver who was driving the Mitsubishi Strada, and not Laboga.
