Satish C. Sekar (born September 1963) is a British author and journalist, and a consultant in forensic evidence. Sekar has specialised since the 1990s in the investigation of miscarriages of justice. His work has been published in newspapers including The Guardian, The Independent and Private Eye, and he has also worked for television documentaries including Panorama and Trial and Error. He has worked on a number of high-profile cases in the UK, including those of the Cardiff Newsagent Three, Gary Mills and Tony Poole (wrongly convicted in 1990 for the murder of Hensley Wiltshire), the M25 Three, and Michelle and Lisa Taylor (wrongly convicted in 1992 for the murder of Alison Shaughnessy). He also worked on the case of the Merthyr Tydfil Two (Donna Clarke and Annette Hewins), presenting scientific findings to South Wales Police regarding the fire that resulted in the police's expert accepting his conclusions that the petrol bought by Hewins that night was not the petrol used in the fatal fire. In 1992, his work helped overturn the convictions of the Cardiff Three and while researching a book about the case, Fitted In: The Cardiff 3 and the Lynette White Inquiry, he uncovered errors in the original evaluation of forensic evidence from the crime scene. His submissions to the Home Office about the DNA evidence were instrumental in reopening the case and the eventual extraction of a DNA profile which led to the arrest and conviction of the real killer, Jeffrey Gafoor, in 2003. The Australian and New Zealand Journal of Criminology said that Sekar's "extraordinary work on the case of the Cardiff 3 [put] academic criminology to shame."
