xelrod: good evening. i'm jim axelrod. we begin tonight with reports of a blind chinese dissident make a 300-mile journey from house arrest to the gates of the u.s. embassy in beijing. his as-yet-unconfirmed presence at the embassy would likely complicate prealations with china just as secretary of state hillary clinton is set to travel there. >> reporter: the u.s. embassy in beijing could be protecting this man,. he fled house arrest last week. neither the u.s. nor the chinese government will confirm if he is in u.s. custody. he was imprisoned after opposing a program forcing women to undergo abortions to conform to china's one-child policy. to keep him silent, authorities kept the outspoken lawyer under house arrest, along with his wife and six-year-old daughter. security forces barred visitors and subjected chen and his wife to regular beatings. after plotting for months, chen made his great escape last sunday. under the cover-up of darkness, the blind 40-year-old lawyer waited until the guards were changing shifts. he then scaled a high wall and made his way to meet an accomplice. froot village in shandong, a network afterrist helped him elude police 300 miles to beijing. yesterday chen released an internet video detailing the abuse they suffered at the hands of plainsclothes police. in one instance, more than a dozen men broke into my house, beat my wife, pinned her down, smothered her with a blanket, and brutally hit her with fists and feet for several hours. he says. they beat me, too. chen said he does not want to leave china. u.s. and chine chooiz officials are believed to be negotiating the terms of his safe release, a system that could affect the country's fragile relationship. >> it is better for mr. chen is the u.s. takes a low public profile on this and works quietly behind the scenes to get him out of china and get his family out of china. >> reporter: well before the daring escape, the obama administration had been focused on chen's case. secretary of state hillary clinton mentioned him in a speech on chinese human rights last november. secretary clinton begins talks here in five days, so this development may well headline her visit. jim. >> axelrod: celia hatton in beijing for us. thank you. what does this mean for u.s.-china relations. we're joined by former undersecretary of state, nicholas burns. nick, no shortage of topics for secretary clinton to take up with chinese leaders when she travels there. how likely is this to elevate human rights on the agenda? >> jim, i think human rights will be on the top of the agenda given the story of guangcheng. there were lot of issues, but this is a dramatic story. if in fact this young man is in american custody, it will dominate the meeting and the chinese and american governments will have to try to work out a resolution of this very important matter. >> axelrod: i guess the question then becomes how does secretary clinton raise the issue? is it done forcefully and publicly, or is it done behind the scenes? >> well, you see today, jim, that the two governments are not even acknowledging that he is in custody, and they're not saying much. that means that they're probably talking. it in private. that's the best way to work out a disagreement, but i think this disagreement can only work out in one way. this young man needs to have freedom, either in china or the united states or elsewhere in the world. i believe the administration will stand up for him, safeguard his rights. and if he is in the american embassy, that's considered american territory, and i think he'll stay there as long as he needs to, to secure his freedom. >> axelrod: nicholas burns, former undersecretary of state, thank you for joining us. >> thank you. >> axelrod: a week-long manhunt is over in washington state. today, peter keller, a heavily armed survivallallist, apparently took his own life after authorities tracked him to an elaborate homemade bunker. more now from terrell brown. >> reporter: last sunday, firefighters responded to a house fire. inside were the bodies of peter keller's wife and daughter, both allegedly shot in the head by cerl as they slept. after the murders, police say 41-year-old cerl, heavily armed with high-powered rifles and handguns made his way into an elaborate 20-foot-long, multilevel doomsday bunker eight years in the making. the sheriff said the search for keller left tactical teams dehydrated and exhausted. >> the terrain and elevation to where this was located is really extraordinary. >> reporter: detectives, working from a picture taken in 2004 from a hard drive in keller's home, were able to narrow their search for the bunker. with no nearby roads, a police helicopter airlifted chainsaws and supplies to break into the bunker yesterday. tear gas renterred no response. but this morning, when police blew the roof off of keller's bunker, they found his body. >> they believe the person has been dead for some time. there's a great deal of blood and a pistol nearby. and they do believe that this is peter keller. >> reporter: court documents say keller turned off his cell phone and withdrew $6200 from his bank account. a witness tells police keller was preparing for the end of the world. terrell brown, cbs news, new york. >> axelrod: now to the economy and detroit where roughly 2,000 people showed up at a job fair at the headquarters of quicken loans. the online mortgage lender is looking to add 1,000 new positions, saigths market has "really turned." even some jobs moved overseas are now heading home but as dean reynolds reports, they come with a high cost. >> reporter: with the assembly line humming at g.e.'s massive appliance park in louisville, kentucky, these days, it's hard to imagine that the place was once headed for closure. >> the water heat cert first new product in this place for 50 years. >> reporter: g.e. had shipped much of its appliance production overseas, relying on cheap labor to bring down costs. chine afs a lucrative source, but now, in the aftermath of the great recession, the american work ser more willing to accept lower wages to get a job. i'm guessing you didn't have, like, a whole array of choices of other places to work, right?
