coffee cup that he had gotten her mcdonald s. he s drinking from the clouds, strikes up a conversation, he just a casual conversation. the suspect and the undercover cop? the suspect in the undercover cop. obviously, mark has no clue what s going on. as i am speaking with him, mark s car gets done and he gets up and leave, and leaves behind the cops because. so police had their sample. and less than 24 hours, they had the results. it s confirmed, it s a match. the same dna from the coffee cup is the dna from the latex glove. does your dashboard just light up when you hear that? can t even describe the emotion of it that we re going to be able to hopefully bring some resolution to the tyrrell family. to excite, are armed with search warrants, they arrested mark porter at his office. how do you take that? you got the wrong guy, this can t be. absolutely not, he said, okay! he turned around, put his hands behind his back. that was the only work.
so they bagged them and sent them off for testing. and the crime scene text uncovered something else that could be a crucial piece of evidence. a discarded latex glove. so, a latex glove on the floor jumped out at you? totally out of place and from talking with everybody that there is no way that gary or jan would have left that glove. there it was right in the middle of the floor for everybody to see. did it belong to the? victims or the killer? nobody knew. so, it s collected, you don t know what it means. we don t know what it means, it was collected and sent to the highway patrol crime lab. they had no idea, no working theory of why the couple had been murdered. but they did have a sequence to the order of deaths. it is hard to believe that gary is shot upstairs if jan is still fully functioning and mobile, that she would ve not called 9-1-1, would not have tried to intervene in some way. speculation tells you she is the first victim. she is bludgeoned to deat
