A Cumberland County Grand Jury indicted a 24-year-old man for murder almost three weeks after a 22-year-old man was shot and killed in Portland, according to a press release from Lt. Robert Martin of the Portland Police Department.

Mark Cardilli Jr., 24, is accused of murdering Isahak Muse after an alleged altercation on March 16 at 1:45 a.m. The incident occurred at 107 Milton St., a home where Cardilli lived with his family, Martin said.
