Four years after a Toyota 4Runner came through the front window of the Apple Store at Hingham’s Derby Street Shops, killing a 65-year-old construction worker and injuring twenty-two other people, a judge ruled Wednesday that Bradley Rein is competent to stand trial. The judge added a caution that is standard and easy to miss: competency is not static and can change. He said he is trying to hold the January trial date and asked the defense to be prompt with any new information about Rein’s condition.
The ruling is a procedural gate, not a verdict on anything. It is also routinely confused with the defense that dominated the summer’s other Massachusetts homicide case. Competency and criminal responsibility are different questions, asked about different moments in time, decided by different people, with different consequences. This piece explains the ruling, the standard behind it, and why a finding of competency tells you almost nothing about how the trial will go.
The case
On November 21, 2022, Rein’s 2019 Toyota 4Runner crashed through the storefront glass of the Hingham Apple Store. Kevin Bradley, 65, a construction worker, was killed. Twenty-two others were hurt, several badly. Prosecutors say Rein told police at the scene that his foot got stuck on the accelerator. He had no alcohol or drugs in his system.
He is charged with second-degree murder, motor vehicle homicide by reckless operation, eighteen counts of aggravated assault and battery with a dangerous weapon, four counts of assault and battery with a dangerous weapon, and reckless operation of a motor vehicle. He has pleaded not guilty. His lawyer has described the crash as unintentional, and prosecutors have said an inspection found no vehicle defect that would explain it.
His bail has been revoked three times while the case has been pending, twice over a GPS bracelet that lost power and left probation officers unable to track him, and again last month after he failed a breath test in violation of his probation conditions. His lawyer attributed that result to mouthwash. Prosecutors said he had been warned against products containing alcohol.
That last episode is what produced Wednesday’s hearing. The defense sought competency testing, arguing the failed test might reflect memory loss rather than drinking.
What competency means
Competency asks one narrow question: can this defendant participate in his own trial right now?
The federal constitutional standard comes from Dusky v. United States, 362 U.S. 402 (1960), which asks whether the defendant has sufficient present ability to consult with his lawyer with a reasonable degree of rational understanding, and whether he has a rational as well as factual understanding of the proceedings against him. Massachusetts applies that standard.
The procedure is in G.L. c. 123, § 15. When a court doubts whether a defendant is competent to stand trial, it may order an examination by a qualified physician or psychologist at any stage after a complaint or indictment, and the court instructs the examiner in the legal standard. If more is needed, the statute allows hospitalization for observation, initially up to twenty days and in no event beyond forty from the initial order. Here the screening was done by a clinician who reported no concerns, and the judge made the finding.
Trying a defendant who is not competent violates due process, which is why a judge must revisit the question whenever genuine doubt arises. That is what the judge meant in saying competency is not static. A defendant found competent in September can be found incompetent in December if his condition changes, and the finding does not bind the court for the life of the case.
How it differs from criminal responsibility
This is the distinction worth carrying away.
Competency is about the present. Can the defendant understand the proceedings and help his lawyer today. It is decided by a judge, on a preponderance standard, and it is not presented to a jury. A defendant found incompetent is not acquitted; the case is paused and he may be committed for treatment, and the prosecution can resume if competency is restored.
Criminal responsibility is about the past. Did the defendant, at the moment of the offense, lack substantial capacity to appreciate the wrongfulness of his conduct or to conform his conduct to the law because of mental disease or defect. That is the McHoul standard, it goes to a jury, and once raised the Commonwealth must disprove it beyond a reasonable doubt. A defendant found not criminally responsible is not convicted and is ordinarily committed to a secure psychiatric facility. We explain that defense in what not guilty by reason of insanity actually means.
Nothing reported in the Rein case indicates a criminal responsibility defense. The defense theory has been that the crash was not intentional and not reckless, which is a challenge to the Commonwealth’s proof rather than an excuse. The memory concerns were raised about his present condition, in support of competency testing, not about his mental state in November 2022.
What the Commonwealth has to prove
The charge that carries the weight is second-degree murder, which in a vehicle case ordinarily rests on third prong malice: that the defendant intentionally did an act which, in the circumstances known to him, a reasonable person would have known created a plain and strong likelihood that death would result. It does not require an intent to kill or to injure. It requires conduct so dangerous that the risk of death was obvious.
That is a demanding standard, and it is the reason vehicle cases are usually charged as motor vehicle homicide rather than murder. Prosecutors have said Rein was traveling at speed in the moments before the crash. The defense says his foot was caught. A jury asked to decide between recklessness and murder in a parking lot crash is being asked to draw a line that the law states clearly and that cases rarely present cleanly.
Second-degree murder carries a mandatory life sentence with parole eligibility. Motor vehicle homicide by reckless operation is a far lesser offense. Both are on the indictment, and a jury may reach the lesser one.
What to watch
The January trial date, which the judge said he is trying to protect and which has already moved more than once in four years. Whether the defense returns with additional evidence about Rein’s cognition, which the judge invited and which would reopen the competency question rather than create a defense. Whether the parties litigate the vehicle itself, since a defect theory that survived inspection is the kind of claim that produces competing expert testimony. And Rein’s custody status, given three bail revocations.
For the families of the twenty-three people struck that morning, Wednesday’s ruling means only that the case can move. It took four years to get to that.
Common questions
What does competent to stand trial mean?
That the defendant has sufficient present ability to consult with his lawyer with a reasonable degree of rational understanding, and a rational and factual understanding of the proceedings. The standard comes from Dusky v. United States, 362 U.S. 402 (1960).
Is competency the same as an insanity defense?
No. Competency is about the defendant’s condition now and is decided by a judge. Criminal responsibility is about his mental state at the time of the offense and is decided by a jury. A defendant can be fully competent and still assert he was not criminally responsible, or be incompetent with no such defense.
Can a competency finding change?
Yes. The judge said as much. Competency is reassessed whenever genuine doubt arises, and a defendant found competent can later be found incompetent.
What is Bradley Rein charged with?
Second-degree murder, motor vehicle homicide by reckless operation, eighteen counts of aggravated assault and battery with a dangerous weapon, four counts of assault and battery with a dangerous weapon, and reckless operation. He has pleaded not guilty and is presumed innocent.
When is the trial?
The judge said he is working to keep it on track to begin in January 2027.
