Chicago P.D. S1E6

Voight and Antonio enlist the help of agents at the Special Victims Unit in New York, Fin,Jenry and Rollins, to help track down the culprit of a series of rape/murders. Burgess has an opportunity to prove herself to Intelligence. Lindsay enlists the help of Halstead to act as her date for her high school reunion to get back at an old rival.While they're en route, Voight orders the whole team into action, and they look into the killer known as the Riverwalk Killer. Intelligence scours the Riverwalk undercover, keeping eyes open for a suspect in a hoodie. Halstead nabs a guy who fits the description, the man is Theo Mitchell but he's just a pickpocket and he quickly denies the rape and murder accusation. Rather than release him, Antonio has him brought in and leverages Theo's knowledge of the Riverwalk to ID possible suspects during the time of the murder and he remembers a certain person who he passed by and how the guy was wearing workout gear but was just stretching the whole time, stating he thinks the guy was most likely scoping out the area. Mitchell initially thought of stealing from him after spotting his nice watch but backed out, on the off chance that the man was a cop or fellow criminal.After Detectives Odafin Tutuola,Jenry Garcia and Amanda Rollins arrive,they reveal that the killer Intelligence is chasing is the same one they are pursuing. They also reveal both in New York and Chicago that a business convention went down each time a murder occurred. With that, Jin brings out a list of 45 guests on the computer and shows Theo the people before he identifies one as the person he saw. It pans out and leads to Jeffrey Baker, a businessman in town for a conference. They bring him in for questioning and his cavalier attitude rubs Halstead and Lindsay the wrong way, until Antonio interrupts the interrogation - another rape occurred on the Riverwalk.
