He was already facing charges of armed and masked robbery, two counts of breaking and entering for a misdemeanor and two counts of trespassing in connection to an October 17 robbery at the 7 Days Food Mart. That store is a short distance from the Stop N Save where Mahaseth was killed a day later.

Bristol District Attorney Thomas Quinn said Coelho was arrested for the 7 Days Food Mart incident October 27. He was due in court Thursday for a scheduled hearing in that case, but due to the new charges the hearing will not take place.

Coelho is scheduled to be arraigned in Fall River District Court on Monday.
