SAN ANTONIO -

A woman who is presumed to have died before a fire destroyed her home Wednesday had sought a protective order against the father of her daughter less than a month ago.

The application for the protective order was filed by Rebecca Gonzales, 29, at the Bexar County court house Aug. 17.

Gonzales, along with her 10-year-old daughter, Samvastion "Sammi" Ochoa, and an as-yet unidentified female roommate, were found dead inside their home on Karen Lane after firefighters put out a fire there.

Police determined all three had been killed before the fire broke out around 3:30 a.m. Wednesday. They are handling the case as a homicide.

According to documents filed in court last month, Gonzales said her daughter told her Conrad Ochoa, 31, had been sexually assaulting her in his home since November. Conrad Ochoa is the girl's father and Gonzales ex-boyfriend, the documents show.

The paperwork shows Gonzales said she notified Child Protective Services about the allegations. The girl was then returned to the custody of her mother.

The case regarding the protective order was scheduled to go to court Sept. 20.

Arson investigators, meanwhile, were seen knocking on neighbors' doors at Conrad Ochoa's apartment complex Thursday morning. They still have not released the cause of the fire.

Police are continuing to investigate the case, as well. They said they have talked to Ochoa and other family members, but they do not have a suspect in the deaths yet.

Friends of Gonzales and her daughter said they plan to hold a candlelight vigil at 7 p.m. Thursday at The Circle School, in the 200 block of Pershing Drive.

According to workers there, Gonzales' family has been involved with the school for the past decade. They said she once worked for The Circle School as a substitute teacher , and Sammi Ochoa had been a student there in the past.
