CHEYENNE, Wyo. (AP) — The cause of death of a teen found dead in Cheyenne's rail yards in January will be listed as undetermined.

The body of Alexander Frye was found with a single gunshot wound to his forehead after searches by hundreds of volunteers. Initially it was suspected that he killed himself, perhaps because of bullying, but a jury convened as part of an inquest on Monday couldn't determine how he died.

The Wyoming Tribune Eagle reported that Frye was found with a gun in one of his hands. However, gunpowder found on him didn't prove that he had fired the gun, only that it had been fired nearby.

Even though the cause of death is being listed as "undetermined", coroner Marty Luna said there is flexibility to re-examine the case if new information arises.
