An unidentified attacker stabbed and fatally shot Perez in San Jose, province of Mindoro Occidental, according to local and international news reports.
The attack took place after Perez's morning show on local DWDO Radio, according to the reports. The perpetrator pretended to seek advice from the journalist, killed him during their conversation, then fled on a motorcycle, according to the reports. Perez, a lawyer and former politician, was declared dead at a local hospital.
Perez's widow, who witnessed the attack, identified a local police official--who is also a bodyguard for a local politician--as the gunman, according to the local press freedom group Center for Media Freedom and Responsibility. Local journalists believe Perez was killed because his radio program had discussed irregularities in local mining and electricity projects.
In February 2010, authorities indicted Officer Darwin Quimoyog in connection with the killing, news reports said.
