BERMAN: A Colorado man suspected of killing his pregnant wife and two daughters is set to be formally charged. Authorities are expected to release his arrest affidavit explaining why investigators believe he did it. Our Kaylee Hartung live in Fredrick, Colorado, with the very latest here. Kaylee.</s>KAYLEE HARTUNG, CNN CORRESPONDENT: Well, John, as this tragedy has unfolded over the course of the past week, that biggest question looming has been why. It was last Monday that Shanann Watts and her two daughters, Bella and Celeste, seemingly vanished from their home. Tuesday, Chris Watts gave an interview to many local media outlets that some characterized as unemotional when he pled for them to return home. Wednesday, he was arrested. Thursday the three victims' bodies found on the property of a petroleum company where Chris Watts worked. Now, over the course of the investigation to this point, authorities have shared very few details with us, in part because a judge has sealed court documents related to the case, including the arrest affidavit. But with Chris Watts we expect formally charged later today by the Well (ph) County district attorney, many more of these shocking details are expected to come to light. Alisyn, Shanann Watts shared so much of her family's life on social media. But as is the case for all of us, social media did not paint a complete picture of life in the Watts' household.</s>CAMEROTA: Oh, my gosh, Kaylee, this story is insane. We'll come to you for more details as soon as you have them. Thank you very much for that reporting. OK, next to an update for you, what's happening with those parents who were separated from their children at the border? The ACLU gives us a status report on their effort to reunite kids.
