If memory serves, it was a slimjim and a screwdriver (or set of screwdrivers?). On its face, there's nothing unusual about them; I've got the same stuff in my shop at home.
But I'm not 17, with a record of B&E, and carrying them around in my pocket, in the evening, in the rain, and looking in the windows of houses that don't belong to me.
Plus, the extra large screwdriver was found in Travon’s backpack along with 12 items of women’s jewelry. The school police never reported Travon to the Sanford police and they sent the device and the jewelery to them as ‘found’ items. It was later determined the jewelry was stolen from an apartment a couple of blocks from Travon’s school.
