Oct. 21, 2011: Nicolas Guaman is indicted by a Worcester County grand jury on a second degree murder charge, a more substantial charge than initially filed by prosectuors, as well as numerous other offenses. If convicted, he faces at least 15 years in state prison on the second degree murder charge alone.

Nov. 1, 2011: Guaman pleads not guilty to all charges, in his arraignment on the charges at Worcester Superior Court. He is ordered held without bail. He later is appointed two defense attorneys, Stuart Hurowitz and Peter Ettenberg.

Jan. 26, 2012: Pablo Guaman, who police say allowed his brother, Nicolas, to drive his truck without a license, is arraigned on a misdemeanor charge in Milford District Court relating to the crash.

He was released to state custody a few days later and ordered to wear an ankle monitoring bracelet.

Feb - May, 2012: A series of pre-trial hearings at Worcester Superior Court, featuring requests by prosecutors and defense attorneys. Among other things, prosecutors received court approval to collect Guaman's DNA, and defense attorneys received permission for a medical evaluation of Guaman. A judge also agrees to allow prosecutors to depose four members of the Guaman family, to secure their testimony should they be unavailable at trial.

June 26, 2012: In a court hearing in Worcester Superior Court, Peter Ettenberg, the lead defense counsel, said his client is not competent to stand trial. He cited a medical evaluation by a neuropsychologist selected by the defense. A court-appointed psychologist is now conducting a complete evaluation of Guaman.

June 27, 2012: Maria Yupangui, the wife of Nicolas Guaman, is deposed in a public session at Worcester Superior Court. Under questioning from a state prosecutor, she said her son, a witness to the events, was traumatized by what happened.

July 26, 2012: A Worcester Superior Court judge decided to close to the public all future depositions of the Guaman family members, as depositions were scheduled to continue. The next hearing in the case was scheduled for Aug. 29.

April 10, 2013: Kenton-Walker releases a decision on the competency question, writing in a 12-page order that the state has not met its burden. She found Dutan Guaman is not competent to stand trial at this time, but also finds that he has barriers to competency that can be overcome. She orders his counsels to hire an appropriate translator — one who speaks and can understand the indigenous Quechua language spoken by Dutan Guaman — who can help him understand the legal process and his attorneys.

April 11, 2013: The case is continued for two months.
