Patrick Moorhead, an analyst with Moor Insights & Strategy, also said it was a matter of time for a high-profile crime to be broadcast through social media.
"Social media provides the quickest and broadest way to disseminate information, good and bad," Moorhead added. "Unfortunately, I think this will turn into a future trend. This will particularly be true if the killer's acts get a lot of attention, as they seem to be."
Terrorist groups have aired video of beheadings and other vicious crimes on social media for some time, he said. What makes this incident stand out is that it occurred in the U.S. and was posted to social networks while the killer was on the run from police.
WDBJ7 Station manager Jeff Marks was live on air this morning and described Flanagan as someone who was "difficult to work with" and showed outbursts of "anger" at the station.
Marks said Flanagan was fired, though he did not say when that happened. "He did not take that well," he added. "We had to call police to escort him from the building."
Flanagan then filed a lawsuit against the station, according to Marks, but his interview was cut short before he could give any details of the lawsuit.
