Doheny Library
On the night of February 16, 1929, Ned and his close friend and personal secretary, T. Hugh Plunkett, were found shot to death in one of the guest bedrooms of Greystone, Ned's Beverly Hills mansion. After his death, his parents donated $1.1 million to USC to build the Edward L. Doheny, Jr. Memorial Library.
Chemistry
Gunshot Residue Analysis
Gunshot Residue (GSR): GSR arises from the cooling and condensation of the materials produced by the combustion reactions within the firearm and can be deposited on the firer, bystanders, and surrounding surfaces in the event of a discharge.
Chemical analysis - combustion reaction from primer that results in lead, barium, antimony byproducts
