Apparently a nearby security camera had footage of the guy planting the bombs:http://www.nytimes.com/2013/04/18/us/bo ... ml?hp&_r=0
They won't say anything more about it, though. Hopefully they'll have him in custody soon.

Domestic terrorists are more likely to target soft targets that represent multi-culturalism, like sporting events where Kenyans and Ethiopians tend to win. Could be some tea-party nut-job, especially considering that it's a Boston (like the original tea party) event promoting brotherhood to all nations.
It may just be that the terrorist didn't have the resources to hit a major target, and thus went for whatever would get the largest body count. That said, if you don't have the information needed to narrow down the suspect list, the statistical likelihood is that it's a bad supremacist or something in a similar vein.
