Searching for lost Indigenous remains: How the Star helped solve a 150 year old mystery

Four Indigenous skulls were gifted from one famous doctor to another almost 150 years ago. Could they still exist?

David Bruser, investigations editor at The Star, joins "This Matters" to discuss the fascinating story.
