MANILA - One of the primary suspects in the hazing death of University of Santo Tomas law freshman Horacio Castillo III took an onward flight to Chicago from Taiwan, the Taipei Economic and Cultural Office (TECO) said Friday.

In a statement, TECO said Ralph Trangia only passed through Taiwan on a transit flight Tuesday and took a connection to Chicago via Eva Air flight BR56.

"Mr. Trangia left Manila on September 19 by BR262, transited in Taoyuan Airport and connected BR56 flight for the USA on the same day," the statement read.

TECO added that it does not know Trangia's current location.

The Bureau of Immigration earlier confirmed that Trangia left for Taiwan on board an Eva Air flight at dawn on Tuesday, a day after news broke about Castillo's death.

Trangia is among members of the Aegis Jvris fraternity who have been placed on an immigration lookout bulletin for alleged involvement in the death of the 22-year-old law student.

The Philippine National Police has said it would ask the Department of Foreign Affairs to cancel Trangia's passport.

Justice Secretary Vitaliano Aguirre II on Thursday said a case must be filed before the court before they could ask the DFA to cancel Trangia's passport.

Meanwhile, two members of the fraternity have surfaced.

John Paul Solano, another primary suspect, surrendered to authorities and denied participation in the hazing. The part-time medical technologist who rushed Castillo to the hospital Sunday morning said he was only called by fraternity brothers to give the neophyte first aid.

Another member, whose name has been withheld, gave his statement to the National Bureau of Investigation (NBI) regarding Castillo's death Friday afternoon.

The 22-year-old Castillo died of massive injuries consistent with hazing, according to an autopsy report.

Castillo's family found his body at the hospital early Monday after receiving an anonymous text message.
