There is certain evidence collected at the site which shows an element of sabotage.

I don't know exactly how many casualties there are. But if a train falls down 50 or 100 feet, there may be many injuries.

One woman was seriously injured and later died in the hospital while 20 or 21 passengers have been injured.

It was a huge, huge explosion. We have collected all the available evidence from the scene and we're are working on that.

Some of the evidence we collected at the (stabbing) scene did lead up to the trailer where we served the search warrant this afternoon. Fortunately, it ended peacefully.

That is what is suspected, but we don't have enough evidence to say for certain. The damage is so bad up there.
