An e-scooter crash in Arlington’s Rosslyn neighborhood has turned fatal, and investigators are still working to piece together exactly what happened.
County police say the collision occurred around 5:32 p.m. on April 18 at the intersection of Langston Boulevard and Fort Myer Drive—a heavily traveled corridor where commuters, buses, and pedestrians all converge during the evening rush.
According to the preliminary investigation, a charter bus was making a right turn onto Langston Boulevard when it struck a woman riding an e-scooter through the crosswalk.
The rider, now identified as Leah Carlomusto, 45, of Arlington, was rushed to a nearby hospital with critical injuries. Despite efforts to save her, she died on April 26.
The driver of the bus, Luis Barreto Irizarry, 45, remained at the scene. Police issued him a citation for failure to yield. He was released on a summons.
Investigators have not yet announced whether additional charges are under consideration.
A Busy Intersection Under Scrutiny
If you know the Rosslyn area, you know this intersection doesn’t slow down. It’s a gateway between Arlington and D.C., with constant bus traffic, tight turns, and a steady mix of pedestrians and micromobility users.
This crash is likely to renew concerns about how scooters, bikes, and large vehicles share the same space—especially in crosswalks where right-turning traffic often conflicts with people crossing.
Arlington has spent years expanding bike lanes and encouraging alternative transportation, but incidents like this highlight the friction points that remain.

The Arlington County Police Department says the crash is still under active investigation. That means detectives are reviewing evidence, including potential surveillance footage, vehicle data, and witness accounts.
Anyone who saw the crash or has information is asked to contact Detective J. Trainer at 703-228-4185.
