Boston Police report that Tanjim Siam, 24, who was shot at the M&R convenience store on July 14, died today.
A Lynn man, already locked up after his arrest for another gunpoint holdup, in Brockton, was charged earlier this month with Siam's shooting.
Police and the DA's office charge that Stephon Samuel walked into the store and demanded money from the register and then, after he got it, ordered Siam, an immigrant from Bangladesh, into the back of the store and shot him in the head.
His murder mirrors that of Surendra Dangol, a Nepali immigrant who was shot to death in 2009 while working at a Jamaica Plain convenience store even after giving the robber everything he asked for. In that case, Edward Corliss of Roslindale, on parole for the murder of a store clerk in 1971, was convicted of first-degree murder and sentenced to life in prison without parole.
