Linda Lietaviete murder trial: Alvin Santos found guilty
A man has been convicted of murdering a 16-year-old business student in Bournemouth
Linda Lietaviete was found partially clothed with seven stab wounds to her chest at Horseshoe Common on 13 December.
Alvin Santos, 26, had arranged to meet the Latvian student the previous evening, Winchester Crown Court heard.
Santos, who was unanimously found guilty of murder by the jury, is due to be sentenced on Monday.
Blood tests showed he had taken methylone, an illegal drug which has similar effects to amphetamines or ecstasy, at some time in the previous 24 hours.
He had also smoked cannabis.
The court was told that in police interviews Mr Santos said he had been drinking and chatting with Linda but had become "furious" when she told him she was responsible for him being assaulted in 2010.
He admitted stabbing Linda but said he had "blacked out" during the attack.
The court heard Santos later returned to his flat in Wimborne Road, from where his sister Catherine alerted the authorities after he told her he had stabbed someone and she saw blood on his hands.
Det Insp Marcus Hester, of Dorset Police's Major Crime Investigation Team, said Linda had been the victim of a "violent and sustained attack".
"Linda was highly regarded by her family and college and had many friends. She was a hard-working and loved girl whose life was cut tragically short by the actions of an older man," he said.
Santos had previously pleaded guilty to manslaughter, but this was rejected by the Crown Prosecution Service.
