let s catch you up again on what happened in revere. we know of no other place that they conducted a search on, officials tell me this is the only location that has been searched so far, and it s done without a search warrant. in other words, the auto apartment whom it belonged said it s okay. belonged to a young saudi student 20 years old. that person not regarded as a suspec they wanted to check everything out. this young man injured in the blast. had a leg injury, and he remains in the hospital. still under guard, he is not considered a suspect. one other saudi national, a woman, also injured, not considered a suspect. a lot of different areas they are looking into, chris. and hopefully we ll be getting more on these devices. that could really help trace where these devices came from.
