Underlying the science is the helpful fact that flies go through four main and identifiable developmental stages, from egg (which will generally hatch within 24 hours) to larva (which will feed on the corpse for about five days, then spend another couple preparing to pupate) to pupa (equivalent to a butterfly's chrysalis another seven days) and onwards to adult fly. In Britain, they include the common bluebottle and greenbottle, and they are the forensic entomologist's raw material.
The ones that interest him most, because they are capable of detecting death from as far as 10 miles away and are therefore often the first to find a dead body, are those of the family Calliphoridae, better known as blowflies. A great many species of fly feed, in their larval or maggot form, on what Hall delicately calls "carrion". The principles of forensic entomology, however, are another matter, and they are the same whatever the case. These flies can detect death from 10 miles away Quite a gungey body." Fortunately, perhaps, he is forbidden from disclosing much more: like several of his 50-plus entomologist colleagues at the museum, Hall gets called out to crime scenes by police forces from around the country, but cannot discuss individual cases except in the most general terms. It looked like she'd probably been there for some time. "Quite sweet, in a way.")īut undeniably, he devotes at least some of his time to doing exactly what the guys on the telly do: last weekend, for example, he spent 12 hours on a crime scene in the Midlands. "It's a strange smell, isn't it," he muses, as we enter the malodorous confines of his culture research room, where a host of assorted maggots feast on rotting liver and dog food. (That said, he is not above the odd unnerving observation.

These days, of course, thanks to TV series such as CSI: Crime Scene Investigation and Bones, and movies such as Silence of the Lambs (in which a seriously deranged serial killer memorably places the pupa of a death's-head hawkmoth in the mouth of his victims), the forensic entomologist – a scientist who specialises in studying the insect life on and around a cadaver to ascertain time (and sometimes place) of death – is a rather more familiar figure.Ĭourteous, quick and disarmingly normal, Hall, one of the museum's 300-plus behind-the-scenes scientists who will be showcasing their work at an open evening tomorrow, is nothing like the obsessive, borderline nut-jobs TV apparently thinks bug experts should be.
It was the first time a maggot had been used in a court of law to convict a criminal. That corroborated other evidence in the case, helping to ensure Ruxton's conviction and eventual hanging. Two key errors led to Ruxton's arrest: one of the papers he used turned out to be a special edition, sold only in Lancaster and Morecambe and, on the way home, he knocked a man off his bicycle in Kendal and the police noted his licence plate.īut crucially, the case against the doctor was also much aided by a certain Dr AG Mearns, an expert on insects, who established the date on which the body parts had been deposited in the ravine from the presence of a mass of bluebottle larvae, aged 12 to 14 days, crawling all over them. He loaded his gruesome cargo into his car, and dumped it in a remote ravine more than 100 miles away, on the Scottish Borders.

Putting his professional knowledge to effective use, the good doctor then mutilated the corpses, removing identifying marks such as moles and scars, dismembered them, and wrapped the 70-plus body parts in old copies of the Daily Herald, Sunday Graphic and Sunday Chronicle. The unfortunate maid he suffocated immediately afterwards to prevent her revealing the crime. In a fit of jealous rage, he leapt on her and strangled her with his bare hands. Ruxton, born Buktyar Rustomji, had somehow become convinced that his extrovert companion was having an affair (no evidence was ever found that she was). On 13 March 1936, the Bombay-born GP, admired and appreciated by all in his Lancaster practice, was sensationally found guilty of killing his common-law wife, Isabella Kerr, and their maidservant, Mary Jane Rogerson. Were it not for the maggots, it is pretty safe to say the case of Dr Buck Ruxton, one of Britain's most celebrated prewar murders, would be all but forgotten. "So here," says Hall, with suitable drama, "they are: the Ruxton Maggots." Inside, a handful of small brown bugs bob lifelessly in clear preserving fluid. M artin Hall, genial, white-coated head of research at the Natural History Museum's Department of Entomology, holds a miniature glass phial up to the harsh fluorescent light of his gleaming laboratory.
