A teenage boy was given a minimum of 12 years for killing a woman by punching her and then stamping on her face.
Glynis Bensley was killed outside the Seven Stars pub in Smethwick, West Midlands on 3 September.
The judge at Wolverhampton Crown Court lifted restrictions on her killer, 13-year-old Petri Kurt, being named. However, his picture can still not be published.
A second defendant, Zoheb Majid, was jailed for 10 years for her manslaughter, after being found not guilty of murder.
Judge John Warner said Kurt was characterised as "boastful and not caring less" but also became emotional later on "crying, saying [he] had not meant to do it", according to a BBC News report.
He told Kurti and Majid that Bensley's chance meeting them was an "enormous misfortune".
Michael Turner QC, who was defending Kurti said the boy was "susceptible to the influence of older people," adding that he had "learning difficulties".
Bensley was on her way home from the Seven Stars pub when she was attacked, West Midlands Police said.
Martin Lindop, from West Midlands Crown Prosecution Service, said: "These two defendants had targeted Ms Bensley because she was a vulnerable female who was walking home on her own at night."
After stealing her phone, money, cigarettes and jewellery the pair left her for dead. Kurti stamped on her face so hard his footprint was left on her cheek.
A post-mortem examination revealed that Bensley suffered a fatal head injury, dying from a severe bleed in the brain.
Glynis' sister Dawn, said: "We are a very close and supportive family and always look out for each other - to try and explain how Glynis' murder has affected us is very hard to put into words.
"Glynis was my only sister and best friend - I would describe her as my right arm and I thought we would grow old together."
