Ms. Moullac, a Menlo School graduate, was killed when a truck made a right turn at Sixth and Folsom streets and struck her while she was riding a bike.
The truck driver was not initially cited, but police Chief Greg Suhr said that after an investigation by the police department, the driver was found to be at fault.
Chief Suhr said the case would be presented to the district attorney's office, which will make a decision about whether to charge the driver. The chief said a critical part of the investigation was surveillance video footage of the accident uncovered by members of the San Francisco Bicycle Coalition.
