The FBI and Boston police are asking the public for its help in identifying possible witnesses to the kidnapping of 23-year-old Jassy Correia.

The Dorchester woman was found dead in the trunk of a car driven by 32-year-old Louis Coleman, of Providence. He faces federal kidnapping charges in the case, which carries the possibility of the death penalty. Massachusetts U.S. Attorney Lelling said earlier this month "there is probable cause that [Coleman] did kill Ms. Correia."

Investigators released surveillance video showing four people walking near Tremont and Stuart streets from the February night Correia was abducted after she left a Boston nightclub. In its appeal to the public, the FBI stressed the individuals they want to identify "are not suspected of any wrongdoing."

The footage authorities released show the four people are a man and three women who appear to be walking and talking together on a sidewalk just after midnight on Feb. 24.
