I'm not certain but I think one of the R's stated the flashlight was in a drawer in the hall way. If it wasn't in the hallway drawer it may have been a kitchen drawer. On this I am not certain. I don't think they left it out and could not explain why it was on the counter.
I believe when Patsy was being questioned about the flashlight, she was also being shown crime photos of the kitchen dining areas. There was a cabinet or some type of chest just off the kitchen, and that is where Patsy said she kept the flashlight. She was pointing to an open drawer, and told LE that was where it was kept. When LE pointed out that there was obviously no flashlight in that drawer (which had been found open and was open when it was photographed), they asked if it was possible that the flashlight (which Patsy said "looked like theirs" ) was in fact, theirs, since it wasn't in the drawer and the only one in the house was the wiped down one in on the counter. At that point the line of questioning didn't seem to be going anywhere. (as was the case with so much of the R interviews).
