Arianna's mother, 32-year-old Nicole Fitts, disappeared from San Francisco, California on April 1, 2016. She was last seen after her shift at Best Buy on Harrison Street that day.

Later in the day, she exchanged text messages with relatives, saying she was going to Fresno, California with a friend named "Sam." Her family was puzzled by this, as Nicole didn't know anyone named Sam and she didn't have a car.

In the early morning hours of April 2, there was a post to Nicole's Facebook reading, "Spending time with my 3 year old need this brake." Her family doesn't think she actually wrote it; Arianna was two, not three, and Nicole wrote with good grammar and spelling.

Nicole has never been heard from again. Her family reported her missing on April 5; they said they couldn't find Arianna either.

On April 8, Nicole's body was found in a shallow grave in McLaren Park, covered by a piece of plywood with a symbol spray-painted on it. Photos of Nicole and the plywood are posted with this case summary. After Nicole was found murdered, police announced they thought Arianna was at risk.
