Someone was poisoning people on tonight’s episode. They even poisoned a pregnant woman. The wife and baby both died at the hospital. The other victim didn’t fare so well either. NYPD eventually turned to the FBI for help. Remy and his team were called in to investigate. They tried to find a common denominator. The first victim was Carlos Hernandez. He was renovating his apartment. He was married and his wife never met or seen the other victim before. The same for Maisy Durst’s husband. He didn’t know Carlos nor did he think his wife did. Maisy also wasn’t hanging out much. She was too busy focusing on fixing up the nursery.
The killer seemed to have targeted them because they were both achieving something. One with his new apartment. The other with her pregnancy. The poison wasn’t airborne. It had to have been ingested and four more victims were poisoned the day after those two were killed. The victims all went to the same hospital. They went to St. Michaels. Remy said their serial killer would want to watch the carnage he unleashed and so he knew their killer worked at that hospital. He just didn’t know how the killer was poisoning his victims.
There were some that visited a hardware store. The store offers free lemonade. There was a puncture in the jug and so the feds were worried all water jugs were poisoned. They call the company. It’s called Dazzling Water. They checked the van with the stuff. They found some of the containers were tampered with. It was poisoned with a chemical known as DMN. There was no antidote. It was a horrible way to die and it was all for money. The killer sent a message to a news channel. He demanded ten million or he said he was going to keep killing.
More victims were coming in. He poisoned a sport drinks container at a local basketball game. He was hating people for being happy and he wanted to be paid for it. His message has a code on it. He thought he was so smart only he made several mistakes. The killer has a son. The son figured out it was his dad poisoning people. He saw that cipher. He knew his dad would come up with that and so he confronted him. He tried to get his dad to stop. Yet, he couldn’t convince him because his dad was a killer that got off on watching his victims in pain.
The guy told his son that he was doing this for them. The truth was he was just a monster. He was also lazy. If he dedicated half of his energy towards something good, he wouldn’t need to kill people for money. He didn’t want try out for a new job or go back to school to get a degree. He lived with his dad. His son’s mother walked out on them. He couldn’t maintain a relationship. Everyone thought he was a loser. The one person that had faith in him was his son and he was risking their relationship with all that he was doing.
His mistakes also didn’t stop at just the cipher. He was seen at the basketball court. The person that spotted him was an artist and he got a picture of what he looked like. The killer was identified as Cormac McClure. He was an orderly at the hospital. The feds raided his home. He wasn’t there. His dad was and there. He told them all about his son. He said that Cormac would take someone bumping into him as an insult. He said his son was dangerous. The feds also found Cormac’s plans. He planned on poisoning an apartment building’s water supply.
There’s no telling how many more he’d kill until he was stopped. The Mayor was cracking under the pressure after just ten deaths. They were considering paying him just to stop the murders. Only the feds were getting closer. They found out where Cormac was getting the DMN. He was stealing supplies from the hospital to make his own batch. He had enough material to make gallons of the poison. He could kill thousands with that supply. He was prepared to go that far. His son later snuck out to meet him.
Jason tried to tell his dad to stop. He didn’t want any part in what was about to happen. He didn’t know that the feds were tracking him and so the kid led him to his dad. There was a shootout. Cormac was killed. The whole thing showed his son that the world was out to get them. Cormac had told him just moments before his own death that the world was cruel. No one was looking out for them. They weren’t going to get anything good until they take it for themselves. The kid ran off after his dad died and so the feds were worried that he’d carry out his father’s plans.
His dad was rejected by quite a lot of apartment buildings. His plan could’ve been to attack one of them. The feds called Cormac’s dad. They found which building was the last to reject him. They went to that place and they found Jason about to poison the water supply. Ray was able to talk him down. Jason wasn’t a bad kid. He just watched his father die. He wanted others to feel that pain. He was still a boy. A boy that can be saved and he’ll get better once he gets the therapy he needs. His father was no longer around to corrupt him.
Remy meanwhile chose to invest in a dive bar. He enjoyed his Italian vacation so much that he wanted to go into business for himself and he thought he could update the bar to being something good.
