By Helen Pow PUBLISHED: 18:13 EST, 24 November 2013 | UPDATED: 18:13 EST, 24 November 2013 Two young members of a Boston gang have been convicted of murdering a 16-year-old boy in 2011, simply because his friend lived on a street they deemed enemy territory. Sheldon Mattis and Nyasani Watt, both 20, were found guilty of first-degree murder in Suffolk County on Friday. The verdict gave victim Jaivon Blake's mother Diane Simmons some closure after two years of torment. 'I can relax,' the mother said. 'I'm so happy, just really happy... I'm just glad that justice has been served and that my son and I can be at peace and rest.'
