Shelly Schaad would have what reason to lie about what Michelle Young told her? I'm sure it wasn't a hard sell for Jason to convince her to go with seat buckled - they had a lot at stake for insurance purposes. And again, why would Michelle lie to Shelly, and why would Shelly lie or make up something out of virtual thin air? Telling the trooper she wasn't wearing a seat belt risked a misdemeanor or trouble with insurance claim. Telling Shelly Schaad the truth later, far less risk...and again, what motive would Michelle have had to lie to Shelly, and what motive would Shelly now have to lie? But hey, defense team, impeach the murdered pregnant woman...go ahead.
