SPRINGFIELD — The case of an Adams man, accused of formulating a terrorist plot in support of the Islamic State, will apparently end with a plea rather than continue to trial.

Alexander Ciccolo, 25, who has been held since his arrest July 4, 2015, was expected to take his case to trial, with jury selection scheduled to begin in early June. The trial was expected to start June 19.

The hearing is scheduled for 1 p.m. Monday at the U.S. District Courthouse in Springfield.

Details of any plea agreement or sentencing recommendation were not immediately available Tuesday afternoon.

A message left at the office of Ciccolo's attorney, David Hoose, was not immediately returned.

Ciccolo previously pleaded not guilty to charges of providing material support to a foreign terrorist organization, attempting to use weapons of mass destruction and illegal weapons possession. He also was charged with assault and battery with a dangerous weapon for allegedly stabbing a nurse with a pen during a routine medical screening after his arrest.

Ciccolo's arrest came after he allegedly accepted a small cache of weapons from an FBI informant.

Ciccolo had come to the attention of authorities after his estranged father, a Boston Police captain, alerted them about his son's expressed interest in going overseas and fighting alongside the Islamic State. He had been under surveillance by the FBI for about six months before his arrest, via a camera mounted outside his Adams apartment.

Ciccolo allegedly disclosed to the informant that he planned to build a pressure cooker bomb packed with gunpowder, shrapnel and debris — like the ones used at the Boston Marathon in 2013 — and detonate the device. He also revealed that he planned to attack a target like a college cafeteria in support of the Islamic State, and to broadcast student executions.

After arresting Ciccolo, investigators found at least partially constructed Molotov cocktails in his apartment and a recently purchased pressure cooker.

Ciccolo's charges carry a penalty of up to life in prison. It is not yet clear what either legal team is seeking for a sentence.
