there was no cuts. >> on the night of darrell north's murder, the dallas/ft. worth area was hit with a driving rainstorm causing flash floods and power outages. the storm was so bad, darrell sent his construction crew home early. but he stayed behind because he had a 5:00 p.m. appointment with curtis pope. they were going to discuss quality problems with the swimming pool pope was installing at the hotel. pope was having financial problems, his company was headed towards bankruptcy, and darrell north was his only large client, although it's unclear whether darrell knew this. no one knows what the two men said to each other. but prosecutors believe curtis pope snapped and attacked darrell with a knife. darrell was caught off guard, and struck pope in the face with a paper punch, causing the nosebleed. pope stabbed darrell over 40 times. as he lay dying on the floor, a drop of blood from pope's nose fell on to darrell's pants. >> there's no way he could have explained the way how his blood was dripped on to darrell north's pants. >> we knew we had eliminated any

darrell b. said is it possible that mh 370 could have shadowed sia 68 to avoid radar direction if it went north. >> there is a theory that flight 370 could have linked up with a singapore airlines flight around the time it disappeared and shadowed that plane on its route to avoid radar direction. >> you know, we came across it and looked at it. i feel it sounds like it is plausible. it matches with the data you can find from the online flight trackers. it sounds plausible but at this point it seems like to much conjecture. if i could touch just on what the first viewer asked which was about the pinging. this is a major point largely overlooked. the satellite nav system was pinging. was checking in with the plane's sat/com system. we know this happened at least four times. the malaysian government made a big deal about releasing that data on saturday morning and releasing this arc you have on the wall behind me. that is the most significant piece of information so far. and why haven't they released the previous pings. if we could see where the arcs lay earlier in the flight it's hard to know for
