The day was June 15, 1990. Linda Wallace, a mother of three returned to her Anaheim home after a day at work to find the unimaginable. After entering her home like any other day, Linda found the body of her nine-year-old daughter, Autumn. The young girl was lying on the bathroom floor, she had been brutally murdered and was found to have suffered from a total of 57 stab wounds.
Wallace's home had clearly been raided and looted as well. The family's belongings were strewn across the floor, and a number of items had been stolen. There was no sign of forced entry, which led investigators to believe Autumn had known her killer and had likely invited them inside.
In the coming months, investigators would make a key discovery in the case: Autumn had been killed by an 18-year-old named Rosie Alfaro, an acquaintance of Autumn's older sister.
After being arrested under suspicion for Autumn's murder, Alfaro made a full confession to law enforcement. Rosie knew the Wallace family personally and believed they would be an easy target to rob in order to finance her drug addiction.
Autumn was home alone at the time that Alfaro approached the Wallace household. After Autumn answered the door, Alfaro asked if she could use the bathroom. Alfaro hadn't expected anyone to be home, and seeing that Autumn would be able to identify her to the police, she proceeded to murder her to ensure her silence.
According to her confession, Alfaro took a knife that was situated in the home's kitchen. After leading Autumn into the bathroom by requesting her help cleaning an eyelash curler, Alfaro attacked the young girl, leaving her with dozens of stab wounds. She then left Autumn to bleed to death on the bathroom floor as she sifted through the family's belongings.
Ultimately, Autumn Wallace was killed so that Alfaro could steal roughly $250 in goods.
