The woman accused of turning a crowded MBTA bus into a scene of carnage stood before a Boston judge Thursday and heard her fate: $5000 bail and strict orders to stay away from her alleged victim.

Luz Maria Pineda, 32, pleaded not guilty to a charge of assault and battery on a person over 60 causing injury after prosecutors laid out the shocking details of a September 8 bus ride that ended with a grandmother sprawled on the sidewalk.

It was just after 1 p.m. when Pineda, with her three-month-old baby by her side, tried to push through the exit doors of the Route 28 bus in Roxbury. Prosecutors say the 63-year-old victim stood in her way and refused to move. What followed was a violent outburst that left fellow passengers stunned. Pineda allegedly kicked the woman’s shopping cart, then shoved the grandmother with enough force to send her flying face-first down the stairs and out the door onto Warren Street.

The victim didn’t just fall—she smashed. According to court records, she suffered a concussion, a deep cut to her face, and broken blood vessels in her neck and eye. She remembers none of it. The grisly fall was captured on surveillance cameras and cell phone video, evidence prosecutors say leaves no doubt about the brutality of the shove.

Pineda stood stone-faced as prosecutors described the grandmother’s injuries in detail. The judge, unimpressed by the defense’s claim that this was a misunderstanding, set bail at $5000 and ordered Pineda to stay off MBTA property and away from witnesses. She is due back in court October 3.

The Route 28 is infamous as one of the MBTA’s roughest rides. But this case has horrified even the most hardened commuters—a grandmother bloodied, a baby strapped to the accused, and an ordinary bus turned into a crime scene. Boston riders are now asking the same question: if this can happen in broad daylight on a city bus, what’s safe anymore?
