The 23-year-old man charged with murdering his co-worker at a Peabody restaurant will be held without bail.
Jaquan Huston pleaded not guilty to the first-degree murder charge he faces in the weekend death of 38-year-old Elivelton Dias in the kitchen of the P.F. Chang's restaurant at the Northshore Mall.
Huston's mother, Shawn Maron-Huston, says her son told her he had been threatened by Dias, and he "snapped." Authorities have not disclosed a motive.
Authorities say Huston stabbed the Dias in the back at about 5:30 p.m. Saturday then fled the restaurant. He was arrested at his home.
Family members say Dias was an immigrant from Brazil who had just become a father for the first time about two weeks ago.
Huston is due back in court on Sept. 28.
