Eerie police body cam footage has emerged from the response to the home of NASCAR superstar Jimmie Johnson's in-laws ... revealing his mother-in-law shot herself just as officers arrived.
In the video, obtained by TMZ, officers approach the home of Dr. Jack Janway and his wife, Terry Janway. Cops observe Jack through a window, deceased from a gunshot wound and covered with a blanket. They open the front door, announce their presence and another gunshot is heard from inside the home.
Cops say that shot was from Terry, who died by suicide.
