> When asked by local reporters about the possibility of two gunshots being a suicide, Lyons replied: "It's unusual in a suicide case to have two shots, but it has been done in the past, and it is in fact a distinct possibility." News coverage noted that there were widespread rumors on the Internet at the time that Webb had been killed as retribution for his 'Dark Alliance' series, published eight years before, but Webb's ex-wife Susan Bell told reporters that she believed Webb had committed suicide.

Two self-inflicted gunshot wounds directly through the cranial cavity approaches near impossibility. A gunshot wound to other parts of the head might not be instantly self-incapacitating. It would be incredibly interesting to know more details about what exactly happened, here.

I was unable to find any other details of this case, or of other cases of multiple self-inflicted gunshot wounds to the head.

I'm not sure that's the case. A second round consciously fired would be practically impossible, sure - but if the person is using a semi-automatic handgun (the most common type) and their finger muscles contract automatically upon the disruption to their CNS, I can totally see a second round being fired.
