Police have charged a man with murder in connection with the death of 16-year-old Cheltenham girl Kayleigh-Anne Palmer last month.
Aston Robinson, 18 and of Cheltenham, had been charged with attempted murder before Kayleigh-Anne's death.
The Crown Prosecution Service authorised the charges to be changed. The victim's next of kin have been informed.
Kayleigh-Anne died in hospital after being attacked at an address in Humber Road on Wednesday April 2. Consideration is still be given to whether Robinson should face any charges in relation to Kayleigh-Anne's unborn child, who also died following the attack.
CPS District Crown Prosecutor Allie Longhorn said: "There is sufficient evidence to charge Aston Robinson with the murder of Kayleigh Palmer and that it is in the public interest to do so."
