What sealed the "poaching" title for me, was reading that the first officer notified another of the dead Elk, through private means (cell phone). The second officer then took the Elk to a meat processor for personal consumption.
...Not to mention the fact, that the first officer never reported discharging his firearm, or any of the other pertinent facts requiring an official report.
And, to top it all off... They lied about the incident for a few days, before witness statements had piled so high, they couldn't dig themselves back out.
