0 hello, everyone. i'm ashleigh banfield and we begin in latvia. due south of finland and due west of russia, where rescuers have just plucked horn 200 people off of ice floes that apparently broke away from shore. the bigger of those free floating ice sheets was just off the capital where 181 people stranded on top of it. another one was near a resort town and just as of moments ago, one person was still out on the ice, but not because they couldn't get to him, because he refused to get on the rescue helicopter, instead preferred to wait for a boat. so far we don't know of anyone who has been hurt, but certainly an intriguing story. ice floes breaking off with people stranded. also making news, the acting mayor of brunswick, georgia is in jail this morning. he's under arrest in connection with the murder of antonio santiago, that 13 honesty omonty who authorities say was shot while in his stroller with his mom. james brooks sr. is accused of obstructing the investigation. brooks allegedly wouldn't let a county investigator talk with the mother of one of those teenagers who were charged in the killing. plenty of people fear the dentist with absolutely no rational reason, but this story that we're about to tell you is about a dentist whom the state of oklahoma probably wishes more people would have feared and would have never let within a mile of their mouths. dr. scott harrington is accused of running a practice so disgustingly unsanitary that he may have exposed thousands of patients to hepatitis or hiv. my colleague ed lavendera is on the story live with us in tulsa. ed, the head of the state dental board is saying when inspectors went into this place, they were, and i'm quoting them, physically sick. how much are we finding out about what they found? >> reporter: well, all these investigations or these visits to this dental practice you see behind me have happened over the course of the last two weeks. i'll give you just some of the highlights in the complaint that they have filed against dr. harrington. some of the things that they had found inside. rusted and unsterilized equipment, reused needles, nonsterile gaus, open vials of drugs answer even one drug vial that had expired in 1993. and as you mentioned, when the investigators on on the couple visits that they have made me and speaking with the assistants, they felt sick, and they described the practice here as a menace to the community. so very serious allegations that are being levied against this dentist here in tulsa. >> he's in tulsa, but other patients there other states and other communities have undoubtedly visited his clinic. he's been practicing for 36 years. and apparently without any complaints or previous issues. but what are the authorities doing to find all of his previous patients or at least the ones who might be at most risk? >> reporter: that is the interesting thing. like you say, more than 35 years of practice. nothing on his record. but now what authorities are most concerned with and really pushing on is trying to get in contact and sending letters out in the records they've been able to compile from inside the dentist's office to some 7,000 patients that have visited here over the course of the last six years. and they picked those six years because according to the health officials, the assistants that have worked with him had spent about that much time with him and so they were able to kind of document that far back. so they're trying to get those people to get out and get tested and for possibly being exposed to infections of hepatitis b and c as well as hiv. and they're offering free tests to people, those people who are getting those letters. but that's the real push thousand. not just people here in the tulsa area, but we understand there are several patients that are in out of state, as well. >> and i've just got the complaint that the oklahoma brd of dentistry has made public and inside the investigation, it's pretty remarkable to find that there is an admission here among two of his dental assistants that they were actually performing iv sedations, actually inverting the needles in to patients' arms and reinserting needles into open vials to sort of reinject -- i mean, this is remarkable stuff. could there be criminal activity coming their way? >> reporter: no question this could definitely lead to criminal charges. and what's interesting is that the investigators in that report, it also documents how the investigators were trying to find the certifications and the background of these assistants to kind of see where they were trained, if they were certified to do the kind of work that they could do. and in that complaint, they were unable to find the assistant certifications. so they were not legally supposed to be doing that according to these health officials. so not only does dr. harrington face possible criminal charges, although none have been filed yet, but the people who worked with him as assistants also face possible criminal charges. none have been filed so far, but this is something health officials are already this contact with prosecutors here. >> a whole mess of trouble that that office could be in. ed lavendera, thank you. we'll also talk about some of the actual legal implications in this story, that's later in this hour with our legal duo, sunny hostin and paul callan. other top stories now. north korea's kim jong-un approves a plan to prepare standby rockets to hit u.s. targets. that move comes after those american stelt bombers flu to south korea to carry out a military exercise yesterday just about 50 miles from the north korean border. as the ground continues to rumble and crumble, people north of seattle will have to decide real soon whether they should stay or whether they should get out. a massive landslide has put several homes there at risk. one home has already been lost. homeowners are telling cnn that they moved here for the view and now they're having to move things out. this was not the view they say they had anticipated. okay. this is from the creepy file, folks. take a close look. do you see anything strange?
