Autopsies underway on 3 found dead in Charlottetown fire

Autopsies began Sunday on the three bodies found in the remains of a vacant Charlottetown building engulfed by fire early Saturday morning.

Fire investigators are piecing together how the blaze started in the building on Mount Edward Road, but officials say weather is hampering efforts and it could be another day before they determine the cause.

The victim’s names have not been released, but Charlottetown police say they are all young people. Deputy Chief Gary McGuigan said investigators have started the process of speaking with next of kin.

A Charlottetown police officer spotted the fire around 5:30 a.m. Saturday after finding an injured male outside the building. The officer was told there were people inside.

He tried to go in, but was pushed back by flames and heavy smoke. Firefighters found the three bodies inside.

Police officers will be sent to Nova Scotia to interview the male who was found injured at the scene and then airlifted to hospital in Halifax.

The building lies on land once used as a driving range and car dealership. The property backs onto Charlottetown Mall and is slated to be redeveloped.

Neighbours say young people sometimes use the building as a hangout. The windows were boarded up last year after vandalism at the site.
