Because the relatives have not been informed, DZMM of ABS-CBN exercised full restraint and did not just blurt out the names of the fatalities.

Instead, their reporters and anchors reported how many had been declared dead and how many injured; the names of the hospitals in which the casualties  had been brought and the phone numbers of the hospitals so that the families could confirm or verify. It (DZMM) also released the names of the injured who had been cleared by the hospital as “out-of-danger” so that their relatives could attend to them. Reporters of the news organization also covered the bombing not just from the crime scene or not just by interviewing policemen but went to the hospital so they could confirm their facts first-hand instead of relying on statements of the police. The anchors also did not just report body count but provided context by giving some historical background of the bombings in the city, but restrained from speculating. Stand by for developments.
