Britain: An Angolan teenager has been jailed for at least 30 years for the murders of a woman at a christening and a student teacher
Roberto Malasi, 18, stabbed Ruth Okechukwu, 18, to death in Walworth, south-east London, in September 2005.
Two weeks earlier, he shot Zainab Kalokoh, 33, in the head when his gang raided a christening party in Peckham, south London.
Diamond, 17, and Timy Babamuboni, 15, and Jude Odigie, 16, were detained for at least eight years for manslaughter.
Old Bailey judge Mr Justice Gross imposed indeterminate sentences on the three, saying they represented a "serious future risk to the public".
They were convicted of Mrs Kalokoh's manslaughter and robbery.
The Babamuboni brothers were sentenced as juveniles despite doubts about their true ages.
The judge also recommended Diamond Babamuboni be deported to his native Nigeria at the end of his sentence.
He "strongly urged" the Home Office to consider the other three for deportation.
Malasi, who recently turned 18, was given two life sentences and told he would have to serve a minimum term of 30 years in prison.
