He was involved in indymedia and frequently wrote for Indybay (www.indybay.org).He was hit in the head by a new type of high velocity, extended range teargas projectile. He received severe head injuries, which resulted in part of his frontal lobe being removed. He is currently in a stable condition and has regained a minor level of consciousness but it is still too early to know what the extent of his recovery can be.
