The episode starts with a man watching boxing. He gets a weird text and then goes to his safe. He’s a drug dealer, but he doesn’t want to deal drugs while his kid is awake, so he tells him to go to the sleep. The kid doesn’t listen and watches his father get shot multiple times.
Bull is stalking Izzy’s Facebook until Marissa brings in his 10 am, a pediatrician accused of killing the drug dealer. They have DNA from under the victim’s fingernails that is a 100 percent match, but the doctor swears that he was at home with his family and has never done heroin.
Marissa tells the team. The place wasn’t broken into, so it had to be a person the drug dealer knew. The text he got was from an untraceable burner phone. The gun was found in the Hudson River and they can’t get prints off of it.
Then they start talking about this really cool thing called forensic genealogy. It’s where law enforcement can get DNA from places like Ancestry.com or Familysearch and compare with DNA of suspects. They can use familial matches and the like. I have no joke had a conversation about this twice in the past week before seeing this episode, so it may be cooler to me than to you.
Anyway, there is a question of legality and privacy rights. The way they confront it is by saying that it’s legal with a search warrant. A fact that they cleverly circumvent is that nobody is forced at gunpoint to send their DNA anywhere if they aren’t in prison. You even have to pay for it.
Also, FYI, 95% of jurors are willing to convict based on DNA evidence alone.
Chunk talks to the wife. Family alibis are the hardest to sell to juries. She’s also the one who sent his DNA, which is how they circumvent the above fact. He never knew anything about his ancestry and he wanted to, so it’s not like it was against his will or wishes either though. She does give Chunk an idea though.
She got an email from the company saying that they got a duplicate sample and wanted to know where it came from. This begs the question; how did the police get enough evidence for a warrant? They conned the genealogy companies and the evidence might be inadmissible in court.
The only problem is that the judge is completely biased and will not suppress the evidence, even though she finds it troubling.
Bull tells the team about the Phantom of Hildebrand. It was a woman linked to over 40 crimes, including six murders through DNA. They did eventually find a little old lady in Latvia that fit the DNA evidence. She worked at a cotton swab factory and contaminated the evidence.
They need jurors who go with their gut. The doctor is likeable, and they won’t want to change that initial impression. They also need jurors have pessimism bias. They will put themselves in Michael’s shoes and will be too afraid that it could happen to them to convict him.
The ADA is really perky, and it makes Bull nervous. He wants to know if there is anything that could possibly be relevant that he hasn’t told him.
He took pain meds after an ankle injury: Oxycodone. He got addicted to them. He never wrote the prescriptions for himself, and his wife did make him quit, but oxycodone is the most common gateway drug to heroin, which the drug dealer dealt. The wife is supposed to be the only one who knows, so Bull says that will not put her on the stand, even going so far as to cite spousal privilege.
That doesn’t help, because the ADA has a new witness. It’s the doctor’s neighbor, who prescribed him the oxy. It does not go well.
Back at TAC, the lawyer drinks. Bull doesn’t. Danny has been looking into false positives, specifically a case in California. There is something called DNA migration. We leave DNA everywhere we go and it will attach to people, like the next person to touch the coffee pot or the next person to grab the rail at a subway station. Marisa needs to bring in a DNA expert, who we never see, and Taylor needs to find the mutual point of contact.
Danny brings in coffee and develops a huge girl crush on Taylor. Both the doctor and the drug dealer were at Grand Central Station. She got security footage and even sees the doctor helping someone up, but we can’t see the face. The woman in front of them taking a picture might have.
They put the victim’s son on the stand. It’s highly emotional and he identifies the doctor.
The person that the doctor helped up was a woman. Bull thinks that a deal is the best course of action. The best he gets is minimum of 15 years, but the client has to agree. He goes on this really eloquent speech about himself and what it meant to find his ancestors. They fought in the Revolution with the Americans. I was really afraid that Bull was going to lose right then.
Not the only one. Marisa and Taylor couldn’t sleep and found something extraordinary. The doctor was adopted and no one ever told him. His name is Jackson McKay. Why does this matter? BECAUSE HE HAS A TWIN!!! EVIL TWINS Y’ALL!!!!!!!
His twin is a bad dude, violent and addicted to heroin according to the social worker that they put on the stand. He also knew the victim and the DNA of identical twins is identical. The ADA wants a recess.
He drops all charges. Benny tells the doctor to sue him. The son went to live with some cousins.
There is one small piece of bad news, though. The twin is dead from an overdose. Bull then says the most beautiful thing. DNA is not destiny. We make our own choices, no matter what our natural tendencies may be. We have free will.
Then “Family Affair” starts playing and it’s all happy again.
I know it’s highly unrealistic, but I’m also a huge sci-fi nerd and I don’t care. EVIL TWINS Y’ALL!!!!! 9/10.
