S5·E17 The Inheritors

Musician Jacob Hardy (Nicholas Lea) is strolling with his fiancee Kara Delaney (Stacy Grant) when a meteor explodes over the city. One of the tiny fireballs which rain down seems to chase Jacob, striking him down and penetrating his skull, instantly killing him. Medical Examiner Dr. Ian Michaels (Tom Irwin) conducts the autopsy with the help of his assistant, Ollie Gibb (Don MacKay). He finds an unusual bullet-like projectile lodged in the victim's brain.
