>> they have so much that they have to say. it was really difficult to figure out where do we begin this conversation. we talk about it all. we talk about the first moments which they were taken into custody. they say for 36 to 48 hours they had no idea why they were even being held. but most of all what they wanted to talk about was the fact that they are so grateful, so glad, so happy that these three young women have finally been freed from the grips of the horrible home on seymour street an also what they wanted people to know was that they this in no way had had anything to do with the crimes of their brother but they're afraid now that they'll be forever condemned. listen. do you worry now that people will always suspect that you actually did have a role? is there absolutely. yes. and the people out there that know me, they know that onil as stroe ast rch o has nothing to do with that, would never even think of something like that. i was a very liked person, individual. i've never had any enemies. no reason for anybody to think that i would ever do something like that. it's a shock to all my friends. they couldn't believe it. >> same. i couldn't never think of doing anything like that. if i knew that my brother was doing this, i would have -- i would not -- in a minute, i would call the cops. because that ain't right. but it's going to haunt me down. because people going to think, yeah, pedro got something to do with this. and pedro don't have nothing to do with this. if i knew, i would have reported it. brother or no brother. >> reporter: one of the things that's really very strong that comes out of this interview, both those brothers are close friends to felix dejesus, the father of dina dejesus, one of the women who was held. these two brothers consoled him. they talked with him during those years which he was looking for his daughter, fearing for his daughter. then this find out when they were in jail that their brother allegedly had been holding gina the whole time inside that house that they had been inside, they were shattered and absolutely devastated. continue to be so but they're also under extreme pressure. they can't go home they say because of the death threats made against them. >> martin, how eager were they to speak publicly? how did this interview come about? >> it was extremely difficult. getting in touch was not a problem. i have a lot of contacts here. i used to work in cleveland and there a lot of people who still like me here so that was key. these are men who aren't accustomed to talking to a television camera. their families worried somehow what they said would be misconstrued. when you sit down and talk with them. you know it is coming from the heart. you can see it in their faces and hear it in their voices, they want to get this out because they cannot stand the tout that anyone believes they could have been connected. there is so much more and we'll have that for you. >> be sure to watch martin's full exclusive interview with ariel castro's two brothers tomorrow at 7:00 a.m. eastern on cnn's "starting point." an arrest in the death of 8-year-old layeila fowler. dan simon has more. what was the brother telling police two weeks ago when the investigation started? >> reporter: such a dramatic turn of events. originally the brother said that he was home alone with the sister, that the parents were at a baseball game. that much we know is true. but then the brother says that he heard an intruder around that he noticed his sister had been stabbed. he said that he saw this intruder run away from the house. so there was an assumption by the authorities here and by everyone in the community that they were looking for what the brother described as a 6'0" tall man and somebody who had a muscular build. somebody with gray hair. obviously this community was on edge. talking about a community of only 7,500 residents. when the sheriff came out yesterday and announced that the brother himself was arrested for the crime twlb was a great deal of shock. >> detectives arrested leila's 12-year-old proer brother at th valley springs substation on charges of homicide. citizens of the county can sleep a little better tonight. this is still an active investigation. we know you may have many questions. i will not be providing any information about this investigation at this time. >> reporter: the maybe question today is why, what was going on in this young man's life to make him react in this way allegedly. were there some psychological problems? and also, what evidence do authorities have on the 12-year-old who is not being publicly named yet? was there dna evidence? some type of confession? those answers will come later. >> a very shocking turn in that case. dan simon, thank you. a three-day standoff ended in new jersey with a suspect dead and three hostages freed. police got a call friday to check on the woman who lived in the trenton house with her boy friend and five children when officers arrived the boyfriend grabbed three of her kids and held them hostage upstairs. police burst in early this morning killing the boyfriend gerald tyrone murphy. the mother and her 13-year-old son were already told. police believe they were killed two weeks ago. the womanwoman's fifld child wh 19 was hiding in the basement. remains in a report have been identified in waynesville, indiana. officials are calling it a quadruple homicide but no arrest has been made. in washington, growing outrage from republicans over how the irs treated tea party groups. top irs officials knew as far back at 2011 that agents were singling out non-profit conservative groups and making it harder for them to get tax exempt status. it's all in a new treasury department report expected to come out this week. >> this is truly outrageous. >> reporter: the obama administration is facing growing anger from republicans over the irs' treatment of conservative groups. >> i don't care if you are a conservative, a liberal, a democrat or republican, this should send a chill up your spine. >> starting as early as march 2010, organizations with tea party, or patriot, in their names were among those singled out for extra scrutiny. subjected to long delays and mountains of paperwork when applying for tax exempt status. >> it contributes to the profound distrust that the american people have in government. >> reporter: some irs officials knew about this practice as early as june 2011. according to an irs inspector general's report expected to be released this week. but then irs commissioner douglas shul man said this to congress in 2012. >> yes, i can give you assuranced. we pride ourselves on being a non-political nonpartisan organization. there's absolutely no targeting. >> reporter: the irs says officials like shulman didn't know about it at the time of his testimony. >> we certainly find the actions taken as reported to be inappropriate. >> reporter: after being pressed about the issue, white house spokesman jay carney released this statement -- if the inspector general find that there were any rules broken or that conduct of government officials did not meet the standard required of them, the president expects that swift and appropriate steps will be taken to address any misconduct. members of congress are promising more investigations. >> but the irs can target the right, one year target the left. we want to make sure that never happens in america. >> athena jones joins me live. when they talk about extra scrutiny for tea party groups what kind of measures are we talking about here? >> well, there are all sorts of examples. most of them have to do with these groups feeling like they were being buried in paperwork. i had a chance to speak to the co-founder of a group called tea party patriots, one of the nation's largest tea party organizations. she said at one point the irs asked to seefb all of the postings on their facebook fan page. that means all of the comments posted by more than 1 million facebook paifans. thousands of pages of information to be handed over. that's just one example. >> athena jones, thanks. three women freed from a decade of horror in cleveland are asking for privacy today. you're going to hear from a father who lost his own little girl in a brutal abduction. plus, o.j. simpson is back in the spotlight this weekend back in court. what he's fighting to get. and a woman lost her nose an her ears at the hand of her family. her emotional story of what drove her to survive.
