According to the Affidavit of Probable Cause, police say that Harlow used a Visa card to buy a knife similar to the weapon found at the murder scene, yet the knife Harlow purchased in Virginia Beach was found in the glove box of his BMW in Virginia Beach. What's interesting though, is that police never did find the 'second' knife Harlow and Joe purchased... not in their house, car, or anywhere on their person. So where's the second knife?
I personally think the knife that was found at Bryan Kocis' house is the exact same brand, and model that Harlow and Joe bought just hours before the murder at Wal-Mart. Now wouldn't that be an(other) odd 'coincidence'?
Now knowing that two knives were purchased right before the murder, one has to wonder if both were used in the slice and stabs, or only one?
Perhaps Harlow and Joe figured out that they were in fact being video taped at the pawn shop, so they assumed the purchase could come back to haunt them... and decided to purchase the murder weapon at the Wilkes-Barre Wal-Mart, figuring it would be 'safer'... or... maybe Harlow and Joe both had knives, and one of them forgot to take their's after leaving Bryan's house... or... I could go on and on... what do you think?
