Connecticut ? A fast-moving fire destroyed a large apartment complex early Saturday in Norwich, Conn., and authorities were looking for dozens of people reported unaccounted for.

No deaths had been confirmed, but Fire Chief Ken Scandariato said he couldn’t rule out that some residents might not have escaped.

He said Saturday morning that 105 of the estimated 150 residents of the Peachtree Garden Apartments had been located. Some may have gone to stay with friends and relatives, he said, adding: “It’s a question right now. It’s in question.”

The wreckage was still too hot by late morning to allow the use of arson dogs or cadaver dogs, Scandariato said, and officials expected to be at the scene until at least this afternoon.

Fire and police officials were not giving updates Saturday afternoon. The cause of the fire remained unclear, but officials were treating the blaze as suspicious, said Mayor Benjamin Lathrop.
