Do you have a reference for knowing the firearm was an AR-15? The original CBS Sacramento article[0] (which the above Ars Technica story references), a neighbor was reported as "firing up to 100 machine gun rounds at a home across the street". From this alone, it's pretty ambiguous as to the firearm involved. Granted, often journalists all-to-often misreport "automatic" vs "semi-automatic" and "machine gun" and "assault rifle", so that may be what happened here as well.
