At least two suspected gunmen carried out the assassination. Both arrived at the scene of the crime in a motorcycle(s?) and waited for the victims to get out of their vehicle. This was near Gate 3 of Ateneo and they escaped on foot to cross Katipunan Avenue and walked/ran in the the vicinity of the Varsity Hills subdivision. A private vehicle was forcibly taken and rammed into the subdivision’s De La Rosa gate. One suspect was captured in Aurora Boulevard by pursuing policemen.
