Notorious serial killer Joe Carroll, after being found guilty of murdering 14 female students on the Virginia college campus where he taught literature, escapes from death row. The FBI calls former agent Ryan Hardy to consult on the case, as he was the one responsible for Carroll’s capture in 2003. Ryan, working closely with an FBI team, including Mike Weston and FBI Specialist Debra Parker, piece together the ever-growing web of murders orchestrated by the devious Carroll.
At the very end of episode 3, first season, a little boy is coerced into suffocating a mouse in a jar. We don't actually see the mouse die, but the scene is disturbing.

S2 E6 about 38 minutes in. I'll avoid spoilers, so a man and woman are on the phone arguing and the man hangs up and says to someone else that she's a bit of a drama queen. Woman screams and gets out of the car to be ill. Gagging noises only, you don't see anything as her head jerks down out of shot. Noises last about 5 seconds. S3 E6 About 4 minutes in, Ryan is leaving the prison when he asks the guards to hold on a second. He runs towards the toilets and it's obvious he's going to be ill. Not graphic.
