According to The Wall Street Journal, Gumbs led a lavish lifestyle with the earnings he made by ordering excess toner and fencing it on the side. Police estimate he made off with millions of dollars worth of the fine powder.
Gumbs would order toner from Office Depot and make arrangements to meet the delivery driver in the street, thus bypassing the normal receiving process at Sloan. Gumbs was employed as a receiving clerk and responsible for ordering ink cartridges for the hospital's printers.
According to authorities, Gumbs lead a lifestyle well beyond his $1,065 biweekly paycheck. In addition to driving a new BMW, Gumbs lived at the Trump Plaza and spent generously at retailers like Gucci and Louis Vuitton.
Perhaps if Memorial Sloan Kettering had been under a managed print services contract the hospital would have noticed the unusual orders much sooner. Much of the toner was for machines the hospital didn't even operate.
