According to this article, it looks like a disagreement over texting led to a physical confrontation, which led to one of the participants (a former Tampa Police captain) pulling out a .380 and killing the other.

There aren’t enough details to say whether the shooting could be justified, although it’s doubtful.

What gets me is that the news folks feel the need to add this little gem:

In summer 2012, a man killed a dozen people and injured 70 at a movie theater in Aurora, Colo. Twenty-six-year-old James Holmes is charged in the killings.

Because other than the fact they were both in a movie theater, everything else is the same?
