Female officer in S4 E12 looked like Sindy Cahill
I've been recording the ME TV episodes and watching them. In Home Fires Burning (S4 E12), Bear, Jon, and Sgt. Getraer are talking in the station hallway when a female CHP officer (uncredited) squeezes between Jon & Getraer while smiling at Jon. Jon turns his head to look at her and Getraer turns Jon's head back. The officer looked like Sindy Cahill (played by Brianne Leary), who was last credited as being on the show in S3 E4.
Dean: I am wearing sunglasses at night. You know who does that? No-talent douche bags!
