Former BART Police Officer Marysol Domenici, one of the first transit officers to respond to Fruitville Station on Jan. 1, 2009, to the incident that escalated to Johannes Mehserle's shooting of Oscar Grant, testified Thursday in Mehlserle's second-degree murder trial.
Domenici, who is among a trio of officers fired over the incident, had previously said the shooting could have been prevented if Grant and his friends had followed offiers' commands to comply.
