"I have no doubt that you are a very evil man capable of committing heinous crimes." Judge Peter Rook, BBC News Online, 25 March 2011On 3 March 2011 Delroy Grant appears at Woolwich Crown Court to face 29 charges, ranging from rape, indecent assault and burglary, from 1992 to 2009. He denies all counts, having previously pleaded not guilty at his hearing held at the Old Bailey.The jury hears that during Grant’s initial arrest he suggests to the police they have the wrong man and should be arresting his eldest son, from his first marriage. It’s clear that Grant has awareness of the number of breakthroughs in forensics and DNA. He’s hoping that his son will share the same DNA and instead be convicted for his crimes. The jury are told that Grant’s DNA proves a perfect match to the DNA samples found at the crime scenes.Grant’s first wife, Janet Watson is put in the witness box to hear the shocking revelation that Grant believes he is being framed by her. He alleges that Janet stole semen and saliva from him in 1977 and that after the marriage ends his DNA is stored at a hospital by a male friend. He goes on to say that fifteen years later his wife, out of malice, gives the DNA to someone else, to frame Grant for a string of burglaries across South-East London. It’s a startling web of lies, because in the 70’s the technique to recover DNA from semen and saliva hadn’t been invented. It shows the jury what a desperate man will do to avoid punishment. Paul Laidlaw QC prosecuting tells Grant that “we are already beginning to see that your account falls apart when it is subjected to the most gentle of examinations."While his fingerprints were being taken in the police station it’s revealed in court that he arrogantly remarked “I don't know why you're bothering, I always wear gloves." He took such lengths to avoid detection during his 17-year crime spree, that not one of his fingerprints was ever detected.The jury hear that on the night of his arrest the police found in his Vauxhall Zafira, a crowbar, blue cagoule, fleece, torch, and woolly hat. These are all items linked to crimes carried out by the Nightstalker. To add to this, the police explain that he was wearing a burglar’s kit of two pairs of jeans, two pairs of boxer shorts, three T-shirts and shoes but no socks. This would have allowed him to change appearances quickly, vital in helping him hide his tracks on CCTV footage. The evidence is damning.On 24 March 2011 the jury find Grant guilty on all 29 charges. Police still believe he may have been responsible for another 600 attacks. Judge Peter Rook sentences Grant to 27 years in jail and gives him four life sentences.
