A Utah crime will take center stage on Friday's edition of "Dateline" (8:30 p.m., NBC/Ch. 5) — and, as you might expect, it's a grisly and disturbing story.

You know, the kind that "Dateline" loves to highlight.

It's the case of Darwin "Christopher" Bagshaw, who, in 2012 — at the age of 14 — beat his 15-year-old girlfriend, Anne Kazpzak, to death with a shovel.

Reportedly, Kazpzak told Bagshaw that she was pregnant, which turned out not to be true; he responded by hitting her repeatedly in the head with a shovel and dumped her body in the Jordan River.

Bagshaw, now 18, pleaded guilty in February. Judge James Blanch, who sentenced him to the mandatory 15-year-to-life prison term, called the crime "unspeakably vicious and cruel."

Again, perfect for "Dateline."
