A PayPal account set up for her grieving family revealed that the alleged attacker was a friend of Hancock and called for donations to support her husband Homer and the couple's daughter.
"Reagan Hancock and her unborn baby were selfishly killed by someone Reagan considered a friend. We are trying to raise money for Homer and their daughter," the appeal
stated.
On a Facebook page set up by her family, Reagan's mother revealed that she had been the one to find her daughter.
"I don't have it in me right now to make a long post," she wrote.
"But mainly I am begging for prayers without ceasing for our family. Our beautiful daughter Reagan Hancock and her precious unborn baby girl Braxlynn were murdered yesterday by Satan in the flesh.
"I found her and Marcus and Chris were on scene right after me. Our family, friends, & community are rocked to the core! Our Reagan was one of the most precious people you would ever meet."

Hancock excitedly shared scans of Braxlynn in August, writing: "We are having another sweet babygirl come November the 10th (give or take). She already acts like her daddy & big sister. We cannot wait for our Braxlynn Sage to be here. Daddy is definitely out numbered."
The identity of the suspect has not yet been released. No further information was immediately available.
The Texas Rangers will investigate because the alleged killer took the baby out of state.
