Rita Cosby quoted him as saying "I noticed a car drive up and two young women get out," so he is wrong on that account. He also says "And at that point, the young women were coming back out of the house, getting into the car and driving away." No way that's true either because Mangum was helped/carried to the car with the help of a player. Anything the guy says is suspect Well you know, if Mangum and Roberts had been sitting in the car with the engine running to keep warm (they had on nearly no clothes), he could have come out of his house and seen them turn off the car and get out and simply inferred that they had just driven up without actually seeing the car in motion.
