The two men convicted of murdering a rival gang member in Jamaica Plain while he shoveled snow in 2015 received life terms with the possibility of parole on Monday. On Dec. 1 a Suffolk County jury found Donte Henley, 26, and Josiah Zachery, 20, guilty of second-degree murder of Kenny Lamour, 21, which occurred by the rotary that connects the Arborway and Centre Street. Zachary was also convicted of assault with a dangerous weapon for shooting at, but not hitting, a Boston Police officer who pursued him during a foot chase. Judge Peter Lauriat sentenced each to life in prison with the possibility of parole after a minimum of 20 years, according to Suffolk County District Attorney Dan Conley's office. Zachery was ordered to serve an additional four to five years in prison, which will be served after he has completed the sentence on his murder conviction.
