There are plenty of sayings about family. You can even buy them etched on wood and scatter them around the house. ‘You don’t have to be mad to live here but it helps…’ or just ‘family is everything.’ April Balascio would probably like to make a giant bonfire of these signs.

Edward Wayne Edwards, it turns out, was a serial killer and April had supplied the missing piece for a swathe of cold cases.
