they just said, oh, well, we know who did it, magdi did it. they focused on magdi.threats be the reason ryan's friend offered him a knife? >> the fact that he was offered a knife for his protection by his drug-dealing friend just minutes, or at the latest, hours before the murder of his mother by someone using a knife suggests to me that there was some reason for him to be afraid for his own safety in his own home. >> the defense also attacked ryan's credibility. remember what ryan told us, that one of the intruders said -- >> i know your circumstances. i know what you're going through. i'm not going to kill you. >> it turns out, ryan did not tell that to the 911 operator. why? the defense argued because those words were never spoken and said later to deflect suspicion from himself and his drug connections. one thing was irrefutable and hard to explain, the defense told the jury -- ryan did not check on ariet before he fled the house. >> how does a young man whose mother has come to save him not look in and check to see whether or not he could save his mother before
