BOSTON (CBS) — Rusted out stairs near the JFK/UMass MBTA station have been removed, one week after Boston University professor David Jones fell to his death from the Dorchester staircase while out on a run.

New warning signs went up around the staircase last week. When SkyEye flew over the area on Monday morning, the stairs had been taken down entirely.

Massachusetts State Police said the stairs had been deemed unsafe and had been closed for about 20 months. A jersey barrier and chain link fence previously blocked the top entrance to Columbia Road.

But Jones’ family released a statement saying his death could have been prevented.

The Massachusetts Department of Transportation said the stairs were demolished this weekend.
