Marissa said she got enraged and retaliated, stabbing the pregnant woman and killing her and the child she bore.
Marissa also allegedly stabbed Peñafiels son, Christopher, 2. The boy died Wednesday in a hospital.
Carmelita denied any involvement, saying she just stood outside the house the whole time of the incident.
When Marissa finally emerged from the house and ran, Carmelita said she merely followed her sister.
The victims husband, Alexis Peñafiel, said Marissa intended to rob her wife that day, taking Carmelita as an accomplice. Alexis said the suspects took a total of $11,000 and assorted jewelry valued at P400,000.
The complaints against the sisters were based on the sworn statements of another maid working for Peñafiel, Rosalie Cabaque, as well as that of the victims husband and six officers of the Vistabella Homeowners Association. Cabaque said Marissa and Carmelita arrived at the Peñafiel residence at about 10 p.m. Sunday. Minutes later, the two sisters started to hogtie Imelda and gagged her with masking tape. She said the suspects left her inside the stockroom of the house.
According to Cabaque, it was Carmelita who guarded and then stabbed Imelda in the left breast. She said Carmelita also threatened to kill her.
Cabaque was able to free herself and ask for assistance from the neighbors but the suspects had already fled. Freeman News Service
