Edgar Eugene Pearce (born 1937–38) is a British extortionist and bomber who was convicted of the Mardi Gra bombings, a three-year blackmail and terror campaign in the London area between December 1994 and April 1998.
His parents were unable to pay the fees, and three years later he came back to the family home and attended Norlington Boys' School in Leyton.
From May 1995, Pearce was randomly sending bombs to different targets and addresses, including one to the Barclaycard headquarters in Northampton with a blackmail demand.
After 17 months of inactivity, Pearce resumed his blackmailing and bombing campaign, this time targeting Sainsbury's supermarkets, in the hope of obtaining money from them.
Lawyers acting for Pearce claimed he suffers from Binswanger's disease, a rare form of dementia that can change the way people think.
