Sinas said they are planning to file a case against the teen's boyfriend who has yet to respond to their invitation for questioning.

“And our primary suspect now is the boyfriend. We will ask the subpoena power of the chief PNP para i-summon siya. If dili siya mu (he doesn't) show up, after the subpoena, damputon namo siya (we will apprehend him),” he said.

The PRO-Central Visayas has asked Philippine National Police chief Oscar Albayalde to issue a subpoena against the boyfriend for investigation.

Sinas said they will file a homicide case against the boyfriend should he decline the summons.
