If this is true, a HUGE question:
1.) Why did Morgan not have the keys with her in her purse? According to the news, wallet and cell were found in purse left in lot-NO KEYS. Also, the other girls have been reported as waiting around for Morgan to leave after the show and then driving the car they took to the arena to their next destination. Clearly, one of Morgan's friends had possession of the keys from 8:30 on. WHY?
Do friends know more about Morgan's plans? Maybe she knew she was meeting someone and already had plans for the night that did not involve staying for the concert and leaving with another friend/ride?
Perhaps Morgan could have been using drugs/alcohol and was not the DD that night, hence the friend holding the keys?
Was purse found near lot where car was parked? Perhaps a friend grabbed keys as they were walking in to run back to car to get something (sweater, ID whatever), forgot to give keys back to Morgan. They go into the show and get separated. Morgan forgets she doesn't have keys in bag, starts to feel sick and tells a friend in her group that shes going to the car to get air/medicine/rest. Walks to car in lot, gets there and realizes she doesn't have keys in her bag--now locked out of show and walking by self at night in parking lot in unfamiliar area, enter sketchy figure here...
