At the scene, responders found Hursen, who had been struck by a falling tree and pinned underneath it.

Hursen was extracted from under the tree and pronounced dead at the scene.

Allegheny County Police say crews from the Tree Masters tree service had been contracted to remove trees at a home on Marberry Drive.

While they were removing one of the trees, it fell unexpectedly and struck another tree, which in turn fell and struck Hursen, who was standing about 40 feet away. Hursen was trapped under the tree for a time before he was able to be freed.

Hursen was a Tree Masters employee.

The investigation is ongoing.
