No not really, thats sort of what makes them rogue, they are not habituated, malnurished, neglected as cubs, come from broken dens, etc. they are just out side of the norm or at least the percived norm.
This is my own speculation on what could have been part of the equation. We have been in a drought cycle here in Utah for several years, and one of the by products of the unusual weather cylces is that the ungulates, specifiacaly deer and elk, have their yearly cycles all out of wack. The rut in late fall/early winter has been sped up or slowed down depending on the area, and in general spread out over a longer more undefined time. This unusual rutting cycle, spread over as much as three months vs a few weeks, causes fawn deer and elk calves to be born over a wider period of time some earlier and some later than normal. This in general also slows the growth of the herds. Bears are one of the top predators of fawns and calves, and are quite predatory durring the fawning and calfing period of late spring and early summer, though this of course depends on the area, and the individual bear. This particular bear(American fork) was not starving and was not diseased, but was quite intent on hunting and eating. So my theory, and its just my own, is that this bear may have been acustom to hunting fawns or calves and if none were available, it just moved on to what it saw as the next best thing. Some of the reading that I have done on bear behavior strongly suggests that bears are very individual in both their behavior and learned traits. For example, one bear may have digging marmots from rock piles down to a science, and preferrs to feed itself in this manner, where as another bear may never do this because it was taught to scavenge carcasses or knows it has the ability to take prey with in a certain parameter ie. 50-100 pound mostly defenseless young deer and elk, or possibly other prey with in that parameter.
