A man who allegedly killed a Muni passenger in broad daylight in early August is being charged with murder, assault with a deadly weapon and weapons crimes by the San Francisco District Attorney's Office.

Ilasa Faalogoifo—who allegedly injured another passenger in the bus shooting—has been in custody since his arrest on Nov. 18, and will stay in jail until his trial for public safety reasons. If convicted, he faces 50 years to life in state prison, the District Attorney's Office said Wednesday.

“The crimes that Faalogoifo is accused of are horrifying and are examples of why I am doing everything in my power to restore public safety for our residents,” District Attorney Brooke Jenkins wrote in a statement.

The August shooting marked the city's third in a recent string of homicides and the second aboard public transit this year.

When San Francisco police officers arrived on the scene, they gave medical aid, including CPR, to the two gunshot victims, a 20-year-old male and a 62-year-old female, the first of whom died after being taken to the hospital.
