HOUSTON, Texas (KTRK) -- Twenty-four hours after two people were fatally shot inside an apartment leasing office, Houston police say they still have no arrests and no clear motive.

The family of one victim, 67-year-old leasing agent Rosie Ybarra, is pleading for answers and justice.

Ybarra, a mother, grandmother, great-grandmother and foster mother, worked at the Park at Woodlake Apartments in west Houston.
