let's see.... not sure what time you got cut off... but the final results were:
1) the debutant - was killed by Tanya Danville (her mother's friend). Motive - revenge. She felt that the mother had stolen her boyfriend (the victim's father) the night of their "coming out".
2) the tiger's dinner - was killed by Felix Parker (the guy that was delivering the roses to the zoo). They found a rose thorn in one of the victim's fingers (our new girl found it after it "passed through" the tiger - if you get my meaning... *yuck*) Parker was buying the victim's meat packing plant in order to put up condos - but it appears that the victim changed his mind. When they went to pick up Parker, his place had been broken into and he was missing. Looks like the victim's uncle (that mob-like guy) took justice into his own hands. Mac has sworn to bring him down. Maybe we'll see more of him down the road.
p.s. I really enjoyed the new girl's character too. The actress was on Medical Investigation last year, which I also enjoyed. I'm glad she's found a new gig!
