A fifth person has been arrested by Dallas police in the rape and violent beating of a pregnant teen to force an abortion.

22-year-old Robert Joseph Cayald has now been charged with aggravated sexual assault of a child.

The victim, who was eight months pregnant at the time of the beating, told police she was a virgin before a family member raped her in 2012.

As a result of the rape she became pregnant.

She said that she “did not tell anyone about the sexual assault because … she was embarrassed.”

According to reports, the girl’s relatives found out about the pregnancy between January and March 2013 and “became very nervous and were concerned about … [Child Protective Services] removing children from the residence,” the affidavit says.

After the beating the teen delivered the baby stillborn.

Police say that the adults then took the baby’s body and tried to burn the child on a grill to cover their crime, before disposing of the dead infant’s remains.

Initially, Police arrested four adults that were living in the house with the teen or who were alleged to be involved in the beating and/or disposal of the dead baby’s body.

Police say the victim later identified Cayald as the man who raped and impregnated her in 2012.

The girl was only 13 at the time of the rape.

Dallas Police Department Deputy Chief Gil Garza said he believes they gave identified and arrested all the right people.
