I haven't read an exact answer either, but I noticed page 3 of the ABC article on the girlfriends call has a picture of TM's T-Mobile phone record that shows the girlfriends 2/26 7:12 call followed by a six day gap before the next call. Phone broken during the fight and fixed somehow by the police six days later explains that best I think.I've only read that he didn't answer. His father was the one that said it went straight to voicemail when he tried to call him.
