Overview

• On July 26, Colden Kimber, 28, intervened at the Ocean Avenue and Lee Avenue Muni stop to shield fellow commuters and was fatally stabbed in the right side of his neck.
• Two children aged 8 and 14 witnessed the attack and transit cameras captured the incident, enabling officers to locate Collins covered in blood and arrest him blocks from the scene with the knife recovered.
• Collins is charged with murder with a deadly weapon enhancement and two counts of felony child endangerment and is scheduled for arraignment on August 14.
• Kimber’s family and the cycling community have organized memorials in San Francisco and New York, launched a GoFundMe for his relatives and planned a tribute ride on September 7 at Golden Gate Park’s Polo Fields.
• The case has intensified scrutiny of passenger safety on San Francisco’s Muni system after a recent string of transit stabbings and prompted renewed calls for enhanced security measures.
