Police have been searching for four young men mysteriously gone missing. Two of them last seen together. But tonight the mystery appears to have been solved. After a shocking discovery on a farm that led to one mans confession. Heres abcs eva pilgrim. What do you have to say to these families . Im sorry. Reporter tonight a stunning admission ending a more than weeklong mystery in bucks county, pennsylvania. Mr. Dinardo this evening confessed to the district attorney. He confessed to his participation and commission in the murders of four young men. Reporter the defense attorney for 20yearold Cosmo Dinardo speaking to cameras outside the courthouse, saying his client spared the Death Penalty in exchange for his confession to the district attorney. When you say four young men mean the four young men who were missing . Yes. Reporter since last week local and federal investigators have been scouring the suburban Philadelphia Community in search of four young men who vanished. Weve negotiated this outcome for cosmo to be very honest, forthright, and truthful in what occurred within the last week and a half. Reporter the search for days focusing on this 90acre farm in solberry township owned by dinardos family. Officials making a grim announcement overnight, recovering the body of dean finocchiaro alongside other human remains. We have found human remains in an approximately 1 12 1 2footdeep common grave that we have painstakingly dug with a lot of care so as not to damage any potential evidence. Did he tell police where all four bodies are . Yes. Ill leave that for law enforcement. Reporter finocchiaro along with 22yearold mark sturgis and 21 saerld thomas meo were last seen friday. 19yearold jimi patrick has been missing since last wednesday. I know more than im sharing on the relationships, and i have to keep it that way, unfortunately, to maintain the integrity of the investigation. Reporter officials now putting together a timeline of what they say happened. Authorities say around 4 00 p. M. Friday sturgis went to meet meo. Four hours later license plate readers spotted meos car within feet of dinardos truck. The next day both meo and sturgis failed to show up at work. Where was the sound of these gunshots coming from . Reporter Susan Coleman says she heard gun nooir on the dinardo family property saturday afternoon. All of a sudden we heard this very, very loud boom, boomboom. Then it was like boom, boom, boom, boom. Lots and lots of gunshots that were startling. And sort of reverberated. They were coming from the farm. The farm, the field right over there. They were very violent. And then i could hear in the distance like ah, ah, some sort of commotion. It was a lot of gunfire . A lot of gunfire. Reporter on sunday detectives discover meos car in this garage on the dinardo familys property. With meos lifesaving diabetes medications still inside. This is a homicide. Make no mistake about it. One of the things you obviously want to determine is how did they die. And the prosecutor was very clear today that this is a homicide. So there is forensic evidence at that scene to support a homicide, which im going to guess could well be a firearm. Reporter today investigators were back at the farm delicately digging for more answers. Evacuation crews, network of victim assistance who have been there with our victims families as they mount this roundtheclock vigil. Theyre side by side. Theyre combing through vast fields and buildings. Theyre down 12 foot deep in a hole thats getting deeper by the minute. Theyre tenderly, painstakingly, reverentially recovering the remains of people that they do not even know. Reporter its here amid the stifling heat where a cadaver dog led officials to a common grave. That is a very impressive hole. And clearly he was trying to bury them so deep the hope would be they would never be found. I dont understand the Science Behind it, but those dogs could smell these four boys 12 1 2 feet below the ground. This investigation has been some very good policework. Youve had everything from cadaver dogs to cell phone evidence to video evidence. All coming back to one place, which is him. Reporter as the Community Begins to mourn the loss of four young men, new and Haunting Images are emerging showing dinardo pointing a pistol. Dinardo posted the photos in a group chat, telling acquaintances he wasnt worried that 19yearold dean finocchiaro was still missing, suggesting instead that he was on the run. This is not some impulse homicide. He thought this through. He figured out how to do it. And in the short term he pulled it off. So that is very important in my view when it comes to when youre going to sentence him. Reporter dinardo was first arrested on monday for an unrelated gun charge, then again on wednesday after he bonded out. Officials say the 20yearold allegedly stole a car that blongds to o belonged to one of the missing men. This is for receiving stolen property and theft of a 1996 Nissan Maxima that is owned by thomas meo. Reporter dinardo then tried to sell the car for 500 the day after meo disappeared. Today Cosmo Dinardos attorney appeared before a grand jury at the bucks county courthouse as investigators probed for information. Did he say why . Thatll come out in time. I dont think its appropriate for me out of respect for the families. Reporter dinardo has been known to police since he was 14 years old. A recent Court Document stating he suffered from Mental Illness and had been the subject of involuntary commitment to a mental institution. Prosecutors saying during his arraignment that he was diagnosed with schizophrenia. Can you talk about his Mental Health . I dont want to talk about his Mental Health right now. It wouldnt be a defense to just say i am mentally ill. It would have to be so mentally ill that he literally didnt understand that what he was doing was wrong. And thats the insanity defense. If hes convicted. The only other way his Mental Illness could come up would be hes charged, hes convicted, and during sentencing he pleads for leniency, basically saying that he has real mental challenges. Reporter the bucks County District attorney plans to hold a briefing tomorrow to try and answer questions and bring closure to a community who has gone from searching for their missing men to now remembering them. For nightline im eva pilgrim in bucks county, pennsylvania. Next, why olivia wilde might just be the perfect fit for the broadway adaptation of 1984.

A cold war classic everybody read in high school. Now taking broadway by storm. Down with big brother down with big brother down with big brother reporter not exactly light fare for date night. This show comes from a big place of anxiety. Yes. Anxiety is a buzz word for us. Reporter model and actress olivia wilde is one of the stars. You may remember her from the hit series house. I did good work yesterday. And i was still fired. Reporter where she played 13. Hey, im alex. Reporter before that she was alex kelly on the teen drama the o. C. My passion.

I dont know. It sort of ruins it to give i away. Tell me afterwards. Reporter the production comes at a moment when new york theater is a political hotbed. Vice president elect pence, we welcome you and we reporter last year the incoming Vice President got an earful during the curtain call at hamilton. We are the diverse america who are alarmed and anxious that your new administration will not protect us. Reporter earlier this Summer Shakespeare in the park staged Julius Caesar complete with dark suits and trump ties. That production targeted by trump loyalists. Shame on all of you reporter eager to make a scene. And now this. Yeah. How does this fit into that conversation about politics and art . Its interesting because this is the least literal of all of those in terms of reflecting the current politics. Theres no one dressed up as trump in our show. Were not diverting from the text to draw any parallels to todays world. Its just clear. When the audience hears words like the truth matters, words matter, thats something that they recognize from their own lives. Reporter wilde points to moments like this. Sean spicer, our press secretary, gave alternative facts to that. Reporter to demonstrate the plays relevance. It was of course when Kellyanne Conway said alternative facts that 1984 shot to the top of the bestseller list once again. If ever there were newspeak. If ever there were newspeak it has been coined and perfected by Kellyanne Conway and the entire trump administration. I think people are sort of aware of but they kind of would rather not believe it was that dangerous. We destroy the party with tiny secret acts of disobedience. Reporter in a way olivia wilde was born to play this role. You grew up in a family that would certainly have been of interest to the thought police. Yes. We wouldnt have lasted long. Thought criminals. Unpersoned. The whole lot of us. Reporter her grandfather claude coburn was one of the most famous radical journalists of his time. A contemporary of orwells. Wildes uncle was alexander coburn, a columnist for the Village Voice and the nation. His latest book is the soon to be published encounters with the sphynx. Reporter alex coburn came on nightline in 1990 to argue that communism was alive and well despite the collapse of the berlin wall. I think the ideals that animated the communist movement or the socialist movement 100 years ago are still very much alive. How did that shape who you are and your Political Awareness in dealing with this material . I was raised to question everything. My grandfather was a great journalist, and he had a quote which i love which is believe nothing until it has been officially denied. Its all lies anyway. Remember who were at war reporter the show for all its relevance is based on material that predates the trump era by decades. Wildes costar Tom Sturridge plays the main character, winston. 95 of this text was written in 1949. This play was conceived five years ago in nottingham, england, way before american politics has shaped the way it has right now. Sure. So when people come into this space, they bring all of the things, the burdens of the world on their shoulders, but its their interpretation, not us presenting something to them. When this play was originally adapted, it was mostly about the nsa and about, you know, the revelations of snowden and what people were suddenly realizing about how they were being monitored and what we are willing to give up in the name of security. Reporter part of the play takes place behind the scenes. This is the little room where we retreat to during the show four times. And we run from the stage back here. Everything here is then broadcast live out to the theater. The idea is that winston and julia think theyre in a private place. Reporter but the audience outside is watching it all. Complicit in the surveillance. The rats are everywhere these days. The citys crawling with them. Can we stop reporter the intensity of all this takes a toll night after night. That is what alcohol is for, it turns out. Turns out it was made for broadway. Reporter are your kids in town . Do you go home and tuck the kids in at night . They are in town. Theyre asleep, thank god. Reporter wilde is a new mother. She and her fiance, actor jason sudeikis, have two young children. What do you tell them about this world and what mommys doing . Its very funny because my son loves he loves to perform. He loves the stage. And i could barely tell him any bit of the plot. I look forward to doing something one day that my kids could see. So far i havent chosen one thing that they can see. One day ill get into like toy story 17. Exactly. You can do the voice of a disney princess. Oh, a dream. Reporter you were born in 1984. I was born in 1984. I remember 1984, and i remember in High School Reading that book and thinking, well, George Orwell got it wrong. But now it was like scifi. Right. It was still the distant future. And now its kind of now its current events. Reporter an old drama with new relevance in the era of alternative facts. Im david wright for nightline in new york.

Ucts ive had it up to here its been month after month of fiber. Weeks taking probiotics days and nights of laxatives, only to have my symptoms return. vo if youve had enough, tell your doctor what youve tried and how long youve been at it. Linzess works differently from laxatives. Linzess treats adults with ibs with constipation or chronic constipation. It can help relieve your belly pain, and lets you have more frequent and complete bowel movements that are easier to pass. Do not give linzess to children less than six, and it should not be given to children six to less than 18. It may harm them. Dont take linzess if you have a bowel blockage. Get immediate help if you develop unusual or severe stomach pain, especially with bloody or black stools. The most common side effect is diarrhea, sometimes severe. If its severe, stop taking linzess and call your doctor right away. Other side effects include gas, stomacharea pain, and swelling. Talk to your doctor about managing your symptoms proactively with linzess. Do yno, not really. Head shoulders . I knew that not the one you think you know the tri action formula cleans removing up to 100 of flakes protects and even moisturizes for Sofia Vergara hair and finally tonight, when the law of the jungle isnt enough theres the ninth Circuit Court of appeals. There was some serious Monkey Business at the ninth Circuit Court of appeals when the court was asked to consider who owns these world famous selfies. It makes no sense to allow a monkey to enforce a copyright suit. Reporter the Animal Rights group peta is suing wildlife photographer david slater and his book publisher blurb for Copyright Infringement claiming naruto the monkey is the Rightful Owner after he picked up slaters camera and snapped these selfies. The definition of an authorship turns on he who originates. It doesnt look at the he, she, who or what. Reporter the smiling selfportrait was later sold by slater and also used as the cover for his book about wildlife personalities. And peta says any proceeds from that book or sales of the image should be turned over to benefit the monkey. But according to slaters lawyer, thats bananas. Monkey see monkey sue will not do in federal court. Reporter the case was already dismissed by a lower court last year because naruto isnt, for lack of a better word, human. But if youre going to do that its equally absurd to deny a monkey written notice. Naruto wouldnt need written notice. Maybe the other macaque monkeys in indonesia would. Reporter now its in the hands of a federal Appeals Court to decide whether an animal can hold a copyright. Thank you for watching abc news. And as always, were online at abcnews.
