Still in shock, evidence collected from his daughter and colleagues lead MIT to discover Matt wasn't always on the right side of the law.

Offering to act as their interpreter the priest speaks on their behalf but MIT soon realise the parents do, in fact, speak English. Does the priest know more about the child's murder than he is letting on? And where is their younger child Francis? It's a race against time for MIT who have the chance to save a life instead of being there at the end of one... [Source: MurderInvestigationTeam.com]
