A scalp damaged by bullet holes and a floor on which a murdered man was discovered are on display in a new grisly exhibition on crime.

The spring exhibition runs at the Wellcome Collection, which has previously shown displays on the study of sex, the brain and death.

Forensics: The Anatomy Of Crime features sketches from the site of a murder attributed to Jack the Ripper, murder weapons and the brain of a suicide victim.

In one installation, visitors will be confronted with the sounds from an autopsy of a murder victim. Photographs of people who were wrongly convicted of crimes are also on show.

Superfan’s big action figure score

A Star Wars superfan who made £15,000 selling a single Boba Fett figure is auctioning off another 15 rare items from his collection.

Craig Stevens, 45, clenched his fists with joy when the pristine, unopened bounty hunter toy was sold at auction house Vectis last month. He will return to the sale room in Thornaby, Teesside, to witness the sale of the remaining items, which have an estimate of £28,000 to £42,000.

The most highly valued item this time is a Palitoy FX-7 medical droid from The Empire Strikes Back. A similar item sold last year for £8,400 including commission.

From sandpaper to Crown Jewels

Scientists have got their hands on some of the Crown Jewels, by making their own.

Leading physicists have grown a replica of the Imperial State Crown, a key element of the world famous jewels held in the Tower of London.

They have also managed to reproduce the Duchess of Cambridge's engagement ring.

Scientists working with the Big Bang UK Young Scientists & Engineers Fair, which takes place next month, grew their own jewels from ingredients included in common household items such as drain unblocker, sandpaper and antiseptic cream.

Is White House address so hard?

A convicted child molester has agreed to plead guilty to sending a threatening letter from jail to US president Barack Obama – albeit to the wrong address.

The plea deal was revealed at a status conference on a federal indictment returned last February against 35-year-old Joseph Savage. Savage was in the Fayette County Prison awaiting trial in October 2012 when he sent the letter threatening to “torture and murder” the president and harm an unspecified relative.

The letter was sent to 1,400 Pennsylvania Ave in Washington. The White House, at 1,600 Pennsylvania Ave, received it anyway and turned it over to the Secret Service.

Family buries the right man at last

A US man whose body was left in a state crime lab after a mix-up has finally been buried in Augusta, Georgia.

A coroner says the mistake at the lab in Decatur, outside of Atlanta, led the family of Johnny Morgan Lowe III to bury the wrong man during a funeral in December. Burke County Coroner Susan Salemi is reported to have said the lab failed to return Mr Lowe’s body after a post-mortem.

The body of Louie Caldwell of Clayton County was mistakenly returned and buried by relatives who thought they were laying Mr Lowe to rest.
