SAN FRANCISCO (KRON) — San Francisco police still have no idea what happened to a missing 2-year-old girl whose mother was found murdered earlier this month.

The mom’s coworkers are now coming together to get some answers, and KRON spoke with the Best Buy employees who said they will not give up.

They said this is what Arianna’s mother would want if she was alive–to help find her daughter. Coworkers are putting up fliers in San Francisco and Oakland, hoping someone will recognize Arianna Fitts.

Those friends are focusing on areas Nicole would frequent. For example, the Best Buy on Harrison Street is where she worked, and she would also visit nearby food trucks.

Nicole’s body was found in a shallow grave in McLeron Park. She was covered by a plywood board with a distinct marking on one side.

Police said they have collected 30,000 pieces of information but they still don’t know what happened to Nicole and her daughter.

In fact, investigators aren’t sure where Arianna had been for months.  Coworkers said Nicole worked long hours to support her family.

“Even if you didn’t know her personally, you knew her smile….I never saw her sad,” former Best Buy employee Bree Cruz said.

Coworkers have been spreading the word on social media.

Nicole was last seen on April 1. She was wearing her bright blue Best Buy shirt.

Investigators believe she took Muni on the Third Street corridor around 9:45 p.m. on April 1.

She was not reported missing for another five days.

At this point, police said they have no idea what happened to Arianna.

Friends are hoping she is alive and that someone will see her and call police.
