A search warrant has been issued for a potentially vital clue to a violent crime - a bullet lodged in a teenager's head
Texan prosecutors want the bullet, embedded under the skin in 17-year-old Joshua Bush's forehead, to be removed.
They say it could help convict Mr Bush of the attempted murder of a used-car salesman in a row following a robbery.
The case has raised privacy concerns, with Mr Bush's lawyers fighting to have the bullet remain in his head.
Prosecutors say the 9mm bullet became lodged in the soft fatty tissue in Mr Bush's forehead in a shootout with the car salesman.
Police say Alan Olive returned fire after Mr Bush tried to shoot him.
They say Mr Bush was part of a gang that had tried to take cars from the forecourt.
Identified to police by other gang members, Mr Bush was interviewed.
Mr Olive, a competitive pistol shooter, said a man returned after the police had investigated, threatening to kill him if he gave evidence. The shootout followed.
"I just can't believe I missed him at that distance," Mr Olive says in court papers.
Prosecutor Ramon Rodriguez told Associated Press news agency that Mr Bush "looked like hell. He had a big old knot on his forehead".
