Little sis seemed to change the package 'that almost touched the ground' to something of a size considerably shorter; I did my own tests with a 34+ size and found it came 3-4" from the ground; I'm 6' feet tall, so when subtracting 3" to match Oswald's height the package would be skimming the grass.
No she didn't change anything.
In her W.C. statement She said
"He was carrying a package in a sort of a heavy brown bag, heavier than a grocery bag it looked to me. It was about, if I might measure, about this long, I suppose, and he carried it in his right hand, had the top sort of folded down and had a grip like this, and the bottom, he carried it this way, you know, and it almost touched the ground as he carried it. "
Being the same height as Oswald (5'9"), I tried it with a tape measure locked at 27". Holding the top of the tape, the bottom was nowhere near skimming the grass.
