A deplorable video showing Mackenzie Shirilla mourning her boyfriend after she killed him was posted to her private Instagram account — and then deleted minutes later. Shirilla, 22, is serving two concurrent 15-years-to-life sentences for the killing of Dominic Russo, 20 and a mutual friend, Davison Flanagan, 18, after slamming her car into a brick wall at more than 100 mph on July 31, 2022, and killing them both on impact. 5 Mackenzie Shirilla.
