The first Murano had a side impact collision on the drivers side (the drivers seat and side curtain airbag and dent on the door are evidence). It may have been a rollover since all the glass was cracked, but there is no roof damage (or scrapes) so I am not positive about the rollover (both side curtains should have gone off if it rolled over, and the passenger one appears to be intact). The right rear wheel appears to be off a Pontiac Aztec! Even on a wrecked Murano, its a bit of an insult.
The second Murano hit something kind of high, perhaps a commercial truck. I can imagine it was making a left lane change and the truck suddenly stopped and it ended up being a panic stop offset collision (thats why only the drivers side hood is damaged). The deployment of the front airbag confirms a frontal collision.
The third Murano appears to have spun out and hit the right rear quarter panel area, causing damage also the right rear wheel and frame damage to the hatch cover. The bumper did not appear to sustain much damage, so its not a rear ender. It is interesting to note that the pictures reveal that SL did not have VDC, so if it was a spin out, VDC may have prevented it.
