Special Investigations (Hunters)

Note
Hunters are Special Investigators (or contracted by them). A unit in the Police force. 
A bit like Mulder and Skully from X-Files (been a while since I saw it), more SI from The Dresden Files where the department is super under-funded but you get all the weird supernatural cases to deal with and spin some BS to journalists about what 'really' happened.

Todd Materson - Wick
The Crooked
Missing notes: I think was sent to SI for investigating / cross Don Giovanni. Trying to bust him but due to corruption he failed and was demoted to SI.
Connections
Todd > Sofia
Sofia is Todd's moral compass. When he talks things over with them, their advice keeps them on the straight and narrow
Todd > Isobelle
Isobelle saved Todd's life when a monster had the drop on him. Now he owes them one. Monster: Werewolf.
 
Todd was forced to sever his left arm after being infected in Case 26-0627
 

Sofia Colombo - Sara
The Flake
Investigating a case, she got too close to uncovering something about the police super intendant.
 
Connections
Sofia > Isobelle
Isobelle is somehow tied into it all. Sofia is keeping an eye on them.
Sofia > Todd
Todd came to collect packages from Giovanni's pizza place, Sofia knows Todd from working summer jobs there.

Isobelle Greene - Kala
Professional
A new recruit, also the chief's daughter, kept fumbling so much she got sent to the basement (SI).
Connections
Isobelle > Sofia
On the agency's watchlist. Isobelle has been told to keep an eye on Sofia.
Isobelle > Todd
Met on a mission, worked together unofficially. And successfully. Standard beat cops, parking violation, got the vehicle towed, turned out to be a bank robbery. Hailed as heroes of the day for their accidental towing.
