Djeison Rafael, 21, of Smethwick, is accused of murder and appeared in Birmingham Magistrates’ Court. An application to amend the charges was made following her death.
Rafael has also been charged with two counts of causing actual bodily harm on October 27 and November 7, possession of a Stanley knife on November 7 and assaulting a detention escort officer on November 8.
Rafael was told he was not going to be asked to enter any pleas because the offences are too serious to be dealt with by the magistrates’ court.
District Judge John Bristow told the defendant: “I’m going to send you and your charges to the crown court on November 12”.
