The helicopters were tracking a police chase through the streets of downtown Phoenix when they collided at midday Friday, crashing to the ground in flames and heavy smoke.

KTVK-TV photojournalist Jim Cox and pilot Scott Bowerback were killed, as were KNXV-TV photographer Rick Krolak and pilot Craig Smith.

Police say suspect Christopher Jones will likely be charged with the deaths of the four killed in the crash.
