Matt Restelli was lured from California to Utah and shot seven times in his mother-in-law's home—a murder meticulously planned by his manipulative mother-in-law Tracey Grist, who orchestrated her entire family to execute the crime. Keith Morrison and Josh Mankiewicz dissect how rookie mistakes unraveled the family's alibi, the striking parallels to the Adelson case, and Tracey's chilling ability to control her children like expendable assets in this season 35 premiere of Dateline. Tracey Grist orchestrated Matt's murder to spare her daughter Kate from divorce complications, demonstrating that some family murders stem from pride and control rather than money or love.
