Speaking at the turn-over ceremonies of Task Force Davao, Sara said was not feeling well on Monday and sought her doctor's help.

"Lunes, buong araw iyak ako ng iyak. I lost my identical twins [I've been crying all day last Monday," she said.

"Nag-arrest na heartbeat sa identical twins but one is still fighting," she added.

She said the doctors cannot say yet what caused the fetal deaths.

"Actually daghan siya [doctor] gisulti but they really cannot say what happened," she said.

She said the two fetuses will not be extracted from her womb yet because this might affect the surviving baby.
