Why Did You Kill Me? (2021) review

In 2006, Crystal Theobald was shot and killed in California but the police were having trouble figuring out why it happened, so her mother Belinda and cousin Jaimie used the social media site MySpace to track down members of the 5150 gang that they believe were responsible.  As a nod to amateur sleuthing I suppose it has some merit - and, of course, the whole real life story is horribly sad - but this slightly extended Dateline episode feels a little rushed through, and the use of a scale model of the Riverside neighborhood is too tacky for me (we do have CGI, you know).  Did I mention that many of the "good guys" in this also happen to be meth-heads who tried starting a gang war?
