With the dramatic manhunt underway in Boston for the remaining Patriots’ Day bombing suspect, broadcast networks are scheduling special coverage during Friday prime-time.

CBS just announced a news special titled CBS News Special Report: Boston Bombers. The special will air tonight at 9 p.m. Scott Pelley will anchor the telecast. The special will preempt freshman drama Vegas, which will move to Saturday night at 8 p.m. for this week.

CBS’ release was quickly followed by ABC, which announced a special live report during its usual 20/20 slot at 10 p.m. Elizabeth Vargas will anchor from Boston.

NBC News will likewise use its Rock Center with Brian Williams slot at 10 p.m. to provide coverage.

And of course, the cable news networks — Fox News, CNN and MSNBC — will continue to cover this story around the clock.
