It is one of the most unspeakable crimes a parent can be accused of – shaking their vulnerable baby so badly, that they sustain brain damage, or in the worst cases, die.

Diagnosing Murder is a new investigative podcast by senior writer Michael Bachelard, and producer Ruby Schwartz, that questions whether we can trust the science behind shaken baby syndrome.

Today, Bachelard explains why the diagnosis is in question and whether innocent people are being locked up for a crime they never committed.

And just a warning, some listeners may find the contents of this episode distressing.
