Why Did You Kill Me? is Netflix’s latest true-crime documentary, and it’s got a doozy of a hook: A mother uses fake MySpace accounts to fish for her daughter’s killer. We see a MySpace chat screen, and a disclaimer that all online conversations depicted in the film are recreations derived from interviews. On Feb. 24, 2006, Crystal Theobald was in a car with her brother and boyfriend, driving through their neighbourhood in California. They pulled up to a street corner when a young man drew his pistol and fired into the car. She was struck in the back of the head and killed. Her mother, Belinda Lane, happened to be in a car behind them, and witnessed the entire horrifying scene. The detective on the case, Rick Wheeler, says he wondered why Belinda didn’t seem to be cooperative with the investigation. They came up with an ingenious idea: Create a fake MySpace account pretending to be a young woman, connect with members and see if she can sniff out any leads. She then created another phony profile using a real photo of Crystal, with the name Angel. Jaimie channelled her cousin’s personality into her communiques with the 5150 guys. She then gave the account password to Belinda. Belinda used “Angel” to stir shit among gang members, and “here’s where the story gets even trippier,” she says. It is a taut, gripping chronicle of tragedy that takes an enlightening and poignant turn in its final act.
