ROMULUS, Mich. (AP) — A lawyer representing the owner of a dog that died while traveling with Delta Air Lines says a bloody blanket was among the Pomeranian's belongings.

Attorney Evan Oshan (OH'-shan) says he's awaiting the results of a necropsy on Alejandro. The dog was found dead in its carrier last Wednesday at a cargo facility at Detroit Metropolitan Airport.

The dog was making a temporary stop in Michigan on its way to Newark, New Jersey, from Phoenix. It had been flying in the cargo section.

Oshan said Monday that's he puzzled by the bloody blanket. He says the dog's carrier was also washed, possibly eliminating evidence. Delta says it's reviewing what happened to Alejandro.

Oshan says the dog passed a physical before the flight from Phoenix. The owner lives in New York.
