The investigation into the murder of an 18-year-old Idalou special needs girl has led authorities to grant a protective order for her sister.

According to Everything Lubbock, the protective order was issued and signed Thursday morning (Feb. 25).

While no name has been revealed, the person who's been barred from having contact with the 15-year-old girl is reportedly the same family member named as a potential suspect in a previous CPS case involving Holli Jeffcoat from 2008 and the January 2016 claim by the teen that she was sexually abused and impregnated.

Jeffcoat's sister was removed from her home by CPS the day Holli was found dead.

A protective order is "a civil court order issued to prevent continuing acts of family violence, sexual assault, human trafficking or stalking."

Days after Holli Jeffcoat was found stabbed to death in her Idalou home, it was revealed that she was not only pregnant, but that it was by a family member and her mother had allegedly attempted to cover up the sexual abuse.

Since Jeffcoat's murder, a Facebook community page called Justice for Holli Jeffcoat has been created. A GoFundMe page launched by Jeffcoat's uncle Donovan Reed is attempting to raise funds for her funeral. As of press time, it's raised $780 out of a $10,000 goal.
