"She would say to me and to the rest of the coworkers that she was being abused by her old man at home and that even one day she got kicked out of the house with her kids," Albarado said. "His excuse was that he was the one who paid the rent and if he wanted to he could kick her out of the house whenever he wanted."
She said her heart sunk when she learned that Flores was found stabbed to death Tuesday morning.
"I'm really mad about it because the children will no longer have a mother," Albarado added. "I just hope whoever has the baby will give it back."
