rademacher, a former teacher of german at langley high school. they took his license away after misconduct allegations because of an overseas trip with students. the school district said it did not sponsor, nor did it sanction the trip to germany. and it tried to distance itself from the case. but internal emails obtained by scott mcfarlane and the i-team reveal this those trips had been going on for years. >> chris rademacher's trip wi teaching license and his job. he was investigated for misconduct. allatalcohol to the students, encouraged some of the students to drink to the point of intoxication. strip naked and engage in other inappropriate sexual conduct. he was never charged. police said the alleged incident happened overseas, outside their jurisdiction. in ohio-based company called friendship connection helped organize the trips and like many langley high school parents and students, the organization told us they had no idea about the allegations surrounding rademacher until the i-team reported it in march. fairfax county public schools acknowledged it told only the parents of the suspected victims of the trip in 2014. in a letter to parents, the same head of our i-team investigation said the germany trip was not sanctioned or sponsored by the school district. that was organized privately by rademacher. and the spokesman said the friendship connection not an ov relationship with the district. >> it happened during an open house where all the parents were in attendance. >> march, one parent and others said they assumed the overseas travel was approved by the school because recruitment of students happened in the building. internal emails obtained undered freedom of information act showed langley high school and district administrators have known for years about friendship connection and its germany trips. last year one teacher wrote to the school's principal to say langley has been working with friendship connection for about ten years. that it's proactive in helping students feel safe and secure. and that she trust the organization's judgment. in december a fairfax county school administrator wrote to the principal to say he wanted to get formal approval of the germany trips to get them officially sanctioned by fairfax county public schools. quote since it seems like langley has a relationship with the organization in the past. we submitted a series of questions to fairfax county public schools about the answer them. issuing a statement saying its relationship with friendship connection was quote informal. and the school district said it notified friendship connection in 2014 about the allegations involving rademacher and he was dismissed because of them. we checked, friendship connection says it was never notified and rademacher wasn't dismissed, he resigned. >> do we know where this guy is? >> we've tried over the last few months to reach him and so, too, has friendship connection, nobody so far has succeeded. thanks, scott. hours after the i-team story first aired, back in march, federal prosecutors announced that they were going to formally review the case of christopher radematcher, the school district

anything. >> that's what i'm talking about. >> the overwhelming thoughts around the series is that the caps should have little to no trouble with philly. it's hard to think otherwise when you look at the numbers. but more so than the stats. the capitols team has unbelievable chemistry this year. that started during the off-season when the organization made a few key moves. those moves turning out to be really good. this morning, their first practice of the postseason. there's a difference between the first 82 games and the second season more intensity, you see the t-shirts, they read nothing is entitled and hats, with roman numeral xvi the number of wins it will take to hoist the stanley cup. one of the most playoff-savvy players justin williams is also one of the most encouraging this time of year, carol maloney has more. >> the dressing room is excited. you see our practice today, a lot of whooping, a the lot of skating a lot of guys having fun. >> that fun tempered with determination not to repeat disappointing playoff history. >> almost everyone on this team, well everyone on the team has been through heartbreak. has been through failure. and hopefully is a springboard to success this year. >> nobody in a caps sweater knows more about success than justin williams, he's hoist tleed stanley cups. and come up clutch in every series. >> when you have a nickname, mr. game seven, now mr. perfect -- is that pressure? >> well they're just messing around. that's good locker room talk. and you always make fun of the guys thaw care about, right? you always

the 11th straight time nationals park. the longest home winning streak against one team in that franchise history. daniel murphy is a major reason. he's batsing nearly .500 with two home runs and seven rbi. if you're thinking historic season for murphy, you might want to pump the brakes on that. >> yeah, i probably won't hit however many home runs i'm on pace to hit. i think right now again, talking about the lineup, you just keep pressure on the opposing pitcher. bryce lives on base. he was on base all night last night. graham had four hits and big spots. this is a tough league and those guys over there are good. no matter who we're playing. >> we're not even going to make it just because we won a few ball games here does not mean anything. this means nothing. we'll talk about fast
