As Mason drove back from the hospital that evening he couldn't help but pass by Brad's Diner.
He parked his car a block away and sat there watching the Diner as customers went in and out.
A while later, Brad came out, talking on the phone, he was holding a cup of coffee in one hand.
Whoever Brad was talking to on the phone must have pissed him off because he was shouting, and when he was done making the call, he angrily tossed his cup of coffee, into a trash can that was beside the Diner.
Mason decided to grab the opportunity that presented itself. He waited until Brad had gone back inside, and then he took out a napkin from his glove compartment, he went to the trash can and took out the cup of coffee with the napkin.
He went back to his car with it, and then he drove straight to a standard Laboratory where he requested for a DNA to be carried out. He provided his own sample as well.
