I'm also wondering about the motive. LE has said they are still trying to get to a motive - yet mom says it was a robbery (they wanted her money). I'm wondering if it was mom's meds they wanted. IN NO WAY AM I SAYING MOM WAS SELLING AND DISTRIBUTING ANYTHING!!!! Its just, years ago, the couple that lived down the street from us - the wife was dying with terminal cancer - she had everything including morphine lollipops and all the "good hard stuff". Her husband was always very cautious and very concerned that people would find out and then try to rob them (of the meds). So, could one of these guys (17 yr old prob) have found out that mom had some "good stuff" and he decided he would rob her for it?
JMHO
