on february 21st, 2008, melissa oxley called 911. >> a gun noise like a gunshot? >> it's really bad. >> it certainly was. ben oxley has been shot point-blank in the head and yet melissa, lying in bed right beside him, was unharmed. she ran to alyssa's room to check on her and call 911. 6-year-old alyssa completely unaware of what just happened asked to go see her father. >> i want to go see my dad. you can't. >> ron elgis, the detective who got the call. do you remember getting that call? >> yeah, because i was sleeping. >> he woke up fast to a very big problem. the killing just didn't make sense. >> appearing like a ghost has done this, no evidence, no
