This weekend on TV: 'Prime Suspct' is back on PBS as a prequel

Utah crimes are front-and-center on network TV this weekend — a murder on NBC and a hostage situation that ended with a fatality on ABC.

• "Dateline NBC" (Friday, 9 p.m., Ch. 5) recounts the case of Conrad Truman. In 2012, Truman's wife, Heidy, died in their Orem home of a gunshot to the head.

In 2014, Conrad Truman was convicted of murdering his wife. In 2016, a judge ordered a new trial because jurors in the first trial relied on incorrect measurements of the Truman home.

In 2017, a second jury acquitted Truman.

• "20/20: In an Instant" (Saturday, 8 p.m., ABC/Ch. 4) looks back at the 1994 incident when a schizophrenic man armed with a gun and a bomb took hostages at Salt Lake's main library.

The story is told completely by those who were caught up in the incident — including Lloyd Prescott, the Salt Lake County sheriff's lieutenant who snuck in as one of the hostages and heroically saved everyone.

• Also this weekend, Stefanie Martini follows in the footsteps of Oscar-winning actress Helen Mirren, taking on the role of Jane Tennison — for which Mirren won a two Emmys and three BAFTAs in "Prime Suspect."

But Martini pulls it off, playing Jane as a 23-year-old, newly minted police officer in the prequel "Prime Suspect: Tennison on Masterpiece" (Sunday, 9 p.m., PBS/Ch. 7), the first of three 90-minute TV movies in the best tradition of British crime drama.
