Trace scrapings from O'Keefe's shirts, including apparent fibers, plastic, hair and dirt, collected by Vallier without directly handling the garments and sent to Hanley.
About
Hanley testified that red plastic from the clothing was consistent in color, microscopic appearance, and instrumental properties with sampled red tail-light plastic, while clear plastic was consistent in color and instrumental properties with sampled clear plastic from item 3-1. She said each could have originated from the comparison material or another source with the same characteristics, describing class consistency rather than a unique source identification.
Scrapings and trace material collected from John O'Keefe's orange T-shirt and gray long-sleeve shirt, designated Item 7-18.18. The material included apparent fibers, plastic pieces, hair, and dirt; it was collected by Vallier — who never physically handled the garments directly — and forwarded to trace supervisor Christina Hanley for further analysis.
