the last person known to have seen kenia monge alive before she disappeared. e strange behavior had ramped up detective gurule's suspicions even though the evidence did not warrant an arrest. but now weeks after kenia vanished, gurule had two problems. kenia wasn't the only one who was missing. so was travis. >> he was gone. i couldn't find him anywhere. i was scrambling to find him. i was checking news. i put out a teletype online for law enforcement saying, you know, you find any bodies, give me a call. >> this guy was that dangerous in your mind, that there could be just more -- >> i was calling everybody. i wanted to find out where he was. >> reporter: days passed, then a week. no sign of travis. detective gurule was now working the case almost 24/7. even his wife was involved. >> there was nights where i'd jump out of bed and it would scare her. i'd jump out of bed, grab the phone ring. she'd say, did you hear the phone ring? i'd say, no, i'm leaving myself a message because i need to do this. she said, i'd talk in my sleep about it. kenia's name or travis
