An Allston man who was kidnapped, tortured, and tied to a chair for 11 hours while his assailants undertook a ransom plot studied the faces of those who held him “in case he was allowed to live,” a Suffolk prosecutor said during closing arguments in the four-defendant trial.

JOSEPH CALDWELL (D.O.B. 12/5/82) of Mattapan, DOMONIC CAMPBELL (D.O.B. 4/15/88) of Cambridge, TYON FEASTER (D.O.B. 7/31/84) of Cambridge, and JILLIAN JACQUES, 23 (D.O.B. 3/31/85), of Allston are charged with kidnapping, attempted murder, and arson for the June 1, 2008, incident on Glenville Avenue.

“[The victim] is trying to stay alive,” said Assistant District Attorney Jeremy Bucci, chief of Suffolk DA Daniel F. Conley’s Narcotics Unit. “He’s paying attention to the people who did this to him. He’s looking at their faces in case he’s allowed to live.”

When the man’s captors began to lay down plastic sheeting around him, the prosecutor said, “he decides he’s going to jump off the balcony. What did he say? ‘I’ll die by my hand, not yours.’”

Jacques allegedly lured the victim, then 24, to her Glenville Avenue apartment building under the pretense of buying a small amount of marijuana from him as she had before, Bucci said. This time, however, she insisted that the transaction take place inside her apartment.

“Once he’s inside, he’s met by a person he’s seen before – Joe Caldwell,” Bucci said. “Then Domonic Campbell comes in with a machine gun from behind and orders him into a chair. Joe Caldwell takes [the victim’s] cell phone. And Joseph Caldwell and Tyon Feaster tie him to the chair.”

Jacques later left the scene and went to work.

In the hours that followed, prosecutors say, the victim made contact with his brother. After being told by the kidnappers that they would shoot the victim in the head, the brother was able to raise a little over $4,000 and notified Boston Police of the ransom demand.

At the alleged kidnappers’ instruction, the brother gave the money to two women at Dudley Station. Boston Police took the women, who were both associates of Campbell, into custody; criminal charges against them were later dropped when the investigation revealed that they did not know about the ransom plot.

Meanwhile, Boston Fire Department firefighters and emergency medical technicians were called to Jacques’ apartment building, where a fire alarm had caused residents to evacuate.

“They took a pillow and put it on the stove in order to light a fire,” Bucci said of the kidnappers, who had by then fled the building. “They set rolls of toilet paper on fire.”

Amid the smoky chaos of the scene, Boston firefighters found the victim tied to a chair with electrical cords. He had been so badly beaten that bones around his eyes were broken and he was not immediately able to view photographic arrays because his eyes were swollen shut.

After closing arguments, Judge Frank Gaziano instructed jurors on the relevant law. Jurors then began weighing the evidence. If they do not reach unanimous verdicts by this afternoon, they will return to court at 9:00 tomorrow morning to resume their deliberations.

Bucci tried the case with Assistant District Attorney Joseph Ditkoff, deputy chief of the district attorney’s Appeals Division. Caldwell, Campbell, Feaster, and Jacques are represented by attorneys Tonomey Coleman, Robert Griffin, Pamela Harris Daly, and Joseph Hennessey, respectively.
