Glitter as Forensic Evidence’ Topic for Family Chemistry Night

The Oklahoma Section of the American Chemical Society will host Bob Blackledge of the Naval Criminal Investigative Service for their September Family Night meeting Friday, Sept. 16, at OBU.

Blackledge received his bachelor’s degree from the Citadel and his master’s degree in chemistry from the University of Georgia. Starting with the Florida Department of Law Enforcement’s Tallahassee Crime Lab, Blackledge worked in forensic science for more than 30 years. Stops along the way included the U. S. Army Criminal Investigation Laboratory-Europe and the Naval Criminal Investigative Service Regional Forensic Laboratory. He is the author or co-author of about 50 journal articles and book chapters with an emphasis on trace evidence.

Blackledge’s talk will focus on the use of glitter as the ideal contact trace because of its prevalence in cosmetic products and arts and crafts. He will explain what glitter is, how it is made, the many variations of glitter and the ways it can be characterized and distinguished.

The Oklahoma Section of the American Chemical Society (ACS) will begin its September meeting with a social hour and picnic dinner from 6-7:30 p.m. in front of the Wood Science Building on the OBU campus in Shawnee. Indoor and outdoor games including volleyball and croquet will be available.

The speaker’s presentation on glitter as forensic evidence will begin at 7:30 p.m. in the large lecture hall in Wood Science Building.

The cost of the dinner is $8.00 for section members and visitors, $5.00 for students, and $3.00 for children under 12. All events are open to the public.

To make picnic reservations, contact Dr. Shawna York at (405) 878-2028 or
