Also, unlike the others, the letter in Chile did not contain powder.

The other hand produced a small vial that contained a black powder.

The box contained a powder to cure an unknown illness.

"Look around for another bag like this one containing a white powder," said Rohde.

He opened the bag and found numerous bags containing white powder, which were later identified as heroin.

That raised the possibility that more than one letter contained powder.

In some cases, the canisters contained black powder but could not have been detonated, the officials said.

The second was equally disappointing, containing a coarse gray powder.

There it was found to contain a fuse and smokeless powder, the police said.

Next, a plastic pouch containing a dark powder was hung at the top of the rod.
