Elba Morales, 47, of 7 Fayston St., was arrested Tuesday after she allegedly stabbed her neighbor to death around 12:50 a.m. on Tuesday.

The victim— Sasha Morris, 34— was taken to Boston Medical Center, where she was pronounced dead. At her arraignment in Dorchester District Court on Tuesday afternoon, Morales was ordered to be held without bail.

Prosecutors say the two women were in the apartment of Morris’ boyfriend when they began to argue— and grabbed a knife when the dispute turned physical.

Morales allegedly fled to another apartment in the building and then attempted to leave the area in that neighbor's vehicle, but was stopped by responding Boston Police.

Morales will return to court on Jan. 18.
