Police in San Francisco say they're looking for a 2-year-old girl whose mother was found killed.

Police spokeswoman Officer Grace Gatpandan said at a news conference Saturday night that Arianna Fitts is missing and considered to be at risk. She has not been seen since late February.

The girl's mother, Nicole Fitts, was found slain Friday after being reported missing a week earlier.

No further details were released about the killing or any other circumstances of the case.
