Travis Scott has locked himself away in his Houston home, still devastated by the events that took place one week ago ... according to his attorney. Ed McPherson joined "TMZ Live" Friday to talk about Travis and what happened at Astroworld. While McPherson says there's still a lot of work to be done in terms of the investigation, he remains adamant Travis had no clue as to the dire circumstances -- 8 people dead -- continued to perform.
