He told police the boy had wandered away while in his care for 20 minutes and he found him unconscious. Covering Montgomery County tonight. Were hearing details about a case involving a man who prosecutors say impersonated a cop, then preyed on prostitutes. They say that man actually assaulted one of them. Lets get right to news 4 pat collins. Hes live at the courthouse in rockville. Reporter he posed as a police officer. And then he stabbed and wounded a prostitute with her own knife. I think he was preying on young women who are vulnerable. Young women who might not likely go to police. If they should be robbed or if they should be shadows. Reporter his name is larry steele. Hes 38 years old. Convicted today of stabbing a prostitute in a bizarre encounter where they say he posed as a cop and tried to make a bogus arrest. The scene, the Radisson Hotel in rockville. It began with an exchange of text messages. It went Something Like this. How long are you staying . An hour. My hour is 220. Larry steele posed as a customer in the first part of this effort of his. And later once he was inside the room, and the clothes were off, thats when he claimed to be a police officer. Reporter in this hotel room, they say steele paid the 220. Grabbed the womans arms and said he was a federal cop. There was a struggle. Steele ended up around her neck for protection. Take a look at that knife. It comes with a sheath that makes it look like a pendant. Steele took his from the scene, and was photographed by security cameras at the shady grove metro station. A few minutes ago, i talked to the victim, shes still getting over all of this. She said she had ten staples and 14 stitches in her side as a result of that stab wound.

Employees at several Agricultural Department offices back at work today. Offices in five states, including the Research Center in beltsville maryland were closed because of threats sent on monday. The threats were anonymous and the fbi is investigating their when mexico sends its people, theyre not sending their best. Theyre bringing drugs. Theyre bringing crime. Theyre rapists and some, i assume are good people. Dont worry. Were going to build a wall. That wall will go up so fast your head will spin. Thats donald trump on the day he announces his candidacy and more recently at one of his rallies. Today, a different kind of image. The republican nominee meeting with the president of mexico. And joining us now is nbc news senior Political Editor mark murray. Lets start with part of what trump had to say after the meeting and get your take on the other side. Lets listen in first. And i happen to have a tremendous feeling for mexican americans, not only in terms of friendships, but in terms of the tremendous numbers that i employ in the united states. They are amazing people. Absolutely. And that was what was jarring. And the whole thing was surreal. Beyond the rhetoric of having the way this thing was put together. We didnt get more than 24 hours in advance. Our press corp wasnt able to go. Weve seen a president ial candidates go on the road, barack obama went to the middle east. Mitt romney went to europe in 2012. These things are usually planned out weeks if not months in advance. This was put together right before a big immigration speech. Overall, it did help donald trump in that elevated hes standing right next to the president of mexico the president of mexico treating him like you would and giving him a lot of respect. In that manner, i think it helped donald trump. Where it does hurt is when you play those images of what donald trump said a year ago versus now, there is a lot of rhetorical whip lash there. Will that matter to his base . Will that matter to people that have been with him . It hasnt mattered with his for him to win the presidency, you have to go beyond the base. And i think one of the Big Questions is a lot of the swing voters, a lot of the people theyre trying to woo. People hes had a hard time with suburban mothers. Are they going to listen to the one who was speaking today . Theres been more of the former rather than later. This is hours ahead of his big immigration speech in arizona. What are we likely to hear from that and will he be dropping the mexican president s name . The contrast tonight is going to be a contrast on Hillary Clinton versus what she wants to do on immigration. What does donald trump want to do with the 11 million undocumented immigrants. He has had contradictory statements from him and his campaign. Im looking forward to see what he says of the border, Hillary Clinton wen went to ohio. Clinton addressing a crowd at the American Legion of cincinnati saying the military should be a bipartisan issue. She blasted trumps visit to mexico calling it a photo op. You dont build a coalition by insulting our friends or acting like a loose cannon. It certainly takes more than trying to make up for a year of insults and insinuations by dropping in on our neighbors for a few hours and flying home again. Mexicos president tweeted he invited both trump and clinton. The Clinton Campaign tells nbc news she looks forward to meeting him at the quote, appropriate time. When we come right back tonight on news 4 at 5 00. Good samaritans help lift a fallen tree from a car along rock crpa did a 911 delay make those actions necessary .

Its always seemed calm when we pick up the children. Theres never been any problem. Reporter now, police tell us that crossway school was on lockdown but the lockdown has been lifted. No children teachers or anyone inside the school were in danger. As for the suspect right now hes talking to Montgomery County police detectives.
