HLN has shaken up its weekend primetime.

For years, the network formerly known as Headline News, kept the weekend primetime consistent with weekday programs: Jane Velez-Mitchell at 7pmET, Nancy Grace at 8, and Joy Behar at 9.

But beginning with this past Saturday night, the network debuted HLN Mysteries. The crime block, which aired from 7pmET to 6amET Sunday morning, features crime documentaries including “Body of Evidence: From the case files of Dayle Hinman” and “The Investigators”. These are re-purposed programs from sister channel truTV.

MSNBC has proven over the past few years that crime programming works in weekend prime. In fact, MSNBC regularly wins Saturday and Sunday nights in younger viewers with the Lockup prison documentary series.

In 2006 Time Warner bought the 50% of CourtTV it didn’t own, then renamed the network truTV on Jan. 1, 2008. The network’s “InSession” live court programming was moved from New York to Atlanta in 2009 and co-located with HLN.
