SAN FRANCISCO—After another fatal stabbing at a BART station, officials are adding additional security for passengers. The issue of public safety at BART stations in the Bay Area has become a topic of concern following a spike in violent crime.

The first attack at a BART station transpired in July 2018. Sisters Nia Wilson, and Letifah Wilson, were both attacked at the MacArthur station in Oakland by an unprovoked, John Lee Cowell, 29.

Another fatal stabbing occurred on November 19, where Oliver Williams, 49, was killed after trying to prevent Jermaine Jeremiah Brim of Sacramento, from stealing his shoes, as he slept.

Williams tried to prevent the robbery and pulled out a knife, but Brim wrestled the knife out of Williams’s possession and stabbed him several times with the weapon. Williams was pronounced dead by the time authorities arrived on the scene.
