The murder trial of two men accused of killing a woman in her 20s was halted Thursday morning after court officials learned that two of the four people stabbed in a daytime attack in downtown Boston Wednesday were on witness lists.


Jurors in the trial of Kadeem Foreman and Terrell Rainey, both of Dorchester, were sent home Thursday.


The men are facing murder charges after 24-year-old Toneika Jones was fatally shot in Dorchester in 2010 as she stood in the entryway of an apartment building.


The two witnesses could have been called at either time by prosecutors or the defense attorneys, officials said.


Authorities said there is no evidence that the witnesses were attacked because of their potential testimony.


The stabbings took place Wednesday about 1:40 p.m. near the corner of Beacon and Tremont streets near Government Center. All of the victims were men in their early 20s, police said.

A friend tried to drive one of the victims to a hospital, but they were stopped at Massachusetts Avenue and Boylston Street.

Three of the victims were in stable condition and one was in critical condition. All were expected to survive, police said.

There have been no arrests and police are investigating.
