it's possible that when the boy answered the door his dad was already dead inside. but no one from the tan home called 911, rather, charlie and his mom grabbed their passports and fled the country. >> jean tan and charlie tan left the country, went to canada and came back on that monday before the 911 call was placed. >> so why come back and tell a lie? the prosecution didn't know. a guess, perhaps someone had to run jim tan's business. and this last tidbit, before that four days late 911 call, charlie took the time to first send an e-mail warning to his fraternity brothers. >> he sends an e-mail called "showtime". >> you're going to be hearing from law enforcement. >> yes, yes, you will be surprised. showtime. >> no, the jurors don't buy the self-defense. this was no crime of passion. it was a planned murder.
