Robert is on killer John's tail...

Worried about vulnerable patient Owen, Liam opts for a home visit and calls the police when there's no response.

- 

The cops gain entry and find Owen dead... and on his laptop is a suicide note that confesses to Nate's murder.

What neither Liam nor the police realise is that it's fake.

Having found deceased Owen at the property last week, paramedic John - Nate's real killer - wrote the statement to cover his own back and then left.
