Updated 12:30 p.m. ET: Police report that suspect Vester Lee Flanagan shot himself and is in very critical condition. Flanigan worked at Savannah station WTOC-TV, according to a story posted on the station's site.
Original post: A Twitter account under the name Bryce Williams on Wednesday published messages about and videos showing the fatal shooting of a Roanoke, Va., TV reporter and cameraman during an interview earlier that day.
The account, which was suspended at about 11:20 a.m., began tweeting on Aug. 12 -- generic messages and photos, until Wednesday morning, when it published a series of messages hinting at a possible motive in the attack, which was captured on live TV.
"(Victim) Alison (Parker) made racist comments," the account tweeted, followed by, "They hired her after that???" and "(Victim) Adam (Ward) went to hr on me after working with me one time!!!"
The account then published a series of videos, from the point of view of the shooter, leading up to and showing the early moments of the shooting, which killed Parker and Ward and injured their interview subject.
Many social media users expressed regret over watching the videos.
