Unfortunately, this original suspect did not match the description of the brothers as he was a "dark skinned male".
Also strange is the idea that someone would use a pressure cooker. Theyre constructed of solid steel and are made to withstand an explosion in the event that there is a pressure mishap.
Equally puzzling is the fact that the younger brother still had the backpack after the fact...
Thanks for your thoughtful follow-up; the weight info you shared is a good piece of the puzzle, I'd probably add 5 pounds to your guesstimate for the ball bearing-like materials and other shrapnel material used in the device.
although I know he wrestled in high school, pot smoking and partying college Dzhokhar seems comfortable holding that extra weight for extended periods using just one shoulder to support it.
I've lived in Chicago for about 3 years and while I have heard of Zion, I've never been there (I don't get to the suburbs much; I am very much a city guy).

…the most basic question: Could a pressure cooker fit into a backpack?
…Examining the Backpacks
As someone who regularly carries a backpack, I know what a pain it is to fit larger, oddly shaped things in a backpack (not to mention trying to stuff clothes for a weekend away into a backpack to avoid airline bag check fees...). I also know that when your backpack is heavier than usual you tend to wear both straps or else you're usually dealing with the backpack sliding off the one shoulder you have it on when you walk (and if you are more talented than me and can do the one shoulder routine with a heavy backpack you will definitely alternate shoulders if wearing a heavy backpack for an extended period).
The brothers are White. They are not "dark skinned".
The term "dark skinned" is a much too subjective to claim that Dzhokhar didn't match that description.
Just take a look at the video.
Its not speculation, its the same back pack.

Authorities say they have video of the "dark skinned" man dropping a backpack near the store shortly before the explosion took place.
After getting a calculation that a quart of black powder weighs about two pounds (a very general measurement, because the compound changes weight according to the humidity, and can be loosely or densely packed like any powder), and testing a bag of small nails to find that they weigh about six pounds per quart, and after weighing the pot itself, we found that the whole contraption, fully loaded with four to five quarts of powder, two quarts’ worth of nails and BBs, and a battery and ignition device, would weigh about 30 lbs. So we put a sufficient number of exercise weight plates into our container, shut the lid, and tried carrying it in two backpacks similar in construction to the ones on the two brothers’ backs.
If you look carefully at the first set of photos, showing the surveillance photo of Dzhokhar Tsarnaev and the model wearing a similar pack containing the loaded pot, both packs being slung over the right shoulder using the right strap only, you can see a dramatic difference. There are stress wrinkles under the jacket of the right image on the model, caused by the 30-lb. weight pulling downward, but Dzhokhar’s jacket can be seen to be completely smooth under the strap. His pack is clearly extremely light on his shoulder (which may be why he’s not wearing it slung over both shoulders). As well, you can see that the weight of the pot, pulling down and outward in the model’s bag on the right, is causing a downward sloping of the top of the backpack, and is also causing many vertical stress lines on the face of the bag itself. Dzhokhar’s bag, however, is flat across the top, indicating no such downward pulling force, and it does not exhibit any downward wrinkles on its side. Whatever he is carrying, it is clearly not a 30-lb., or even a 20-lb. cylinder.
Moving to Tamerlan Tsarnaev, check out the model’s slightly larger pack, which like Tamerlan’s is being worn with both straps over the shoulders. Again, the pack on the right, containing the loaded pot, is causing obvious wrinkles on the winter coat where the straps are bearing down on a small section of padded coat. Once again the weight of the straps of the shoulder— this time 15 lbs. per strap—can be seen causing prominent wrinkling on the winter coat worn by the model underneath the straps. The downward sloping of the face of the backpack, and also the vertical stress wrinkles are prominent and clearly visible also. In the video surveillance photo of Tamerlan, however, his coat can be seen to be unwrinkled under the straps, and there are again no vertical stress lines on the face of his pack. Again, it is hard to imagine a 30 or even a 20-lb. weight in the bottom of that pack.
