From the MD Forum:
as i stated on the other thread, i live near flex lewis' gym and the word on the street is that Dallas DIED inside Flex's gym. He was doing cardio late last night with Josh and then Josh went to the bathroom, but when he came back he found Dallas face flat against the floor and not breathing. Again, He died inside Flex Lewis' gym which is WHY Aron Singerman is saying in his video that Flex gave him a call to tell him Dallas had died. He was not in his apartment when he died. Singerman just had to come up with something and did not want to share that he must have died of a heart attack while doing cardio in order to protect his athlete which i highly commend him for. I would have also done the same thing.
However, all facts cant be really hidden because the police report will state exactly where he was found. If he was found inside his apartment or in Flex Lewi's gym, the police report will tell all.
