BOSTON (WHDH) - A new report released from investigators cites no mechanical issues in an elevator accident that killed a woman last month in Allston.

The report, released on Friday, looked into whether a mechanical problem caused the accident in the Allston building that sent two people to the hospital.

Investigators concluded that Boston University lecturer Carrie O’Connor, 38, became trapped between the elevator car and open shaft because of a large box she was moving at the time, the report said.

The inspector said the video shows her struggling to load this large package into the elevator while holding the gate open with her hip.

The package hits the switch that triggers the elevator to start moving.

O’Connor is then seen losing control of the package as it comes off the switch and stops the elevator.

Because the car traveled without the inner gate shut, the front of the elevator shaft was open between the first and basement floors.

The inspector said she then repositions herself and hoists the package up, but it hits the switch a second time causing the elevator to move again.

That’s when it appears she fell backward into the elevator shaft.

Fire officials say she was found pinned between the wall of the shaft and the elevator car.

O’Connor later died as a result of her injuries. She was moving into a new apartment at the time of the accident.
