A manhunt continues for the girls' father, Yaser Abdul Said, 50, wanted in connection with the slayings. A capital murder warrant has been issued for Said.

Authorities are offering a $10,000 reward for information leading an arrest and indictment.

Police documents show that Said had threatened to hurt one of the girls for dating a non-Muslim boy.

Patricia Said, the girls mother, wants her husband brought to justice. She and her son plan to remain in hiding until her husband is caught.

The family had some previous domestic problems, police said.
