Apparently the parents agreed to the arranged marriage in exchange for $20,000.
Bexar County Sheriff Javier Salazar said on Friday: "This young lady, at various times over that time period was subjected to some pretty bad abuse because she didn't want to be married to this person."
"Several times it was reported to us that this young lady was abused with hot cooking oil being thrown on her body. She was beat with broomsticks," Salazar added.
"At least at one point, she was choked almost to the point of unconsciousness."
Al Hishmawi was placed under Child Protective Services custody along with her five siblings, who are between the ages 5 and 15.
The parents were taken into custody on Friday and face charges of continuous violence against a family member.
The man who was arranged to be married to Al Hishmawi may also be charged in the case.
