Commonwealth v. Clancy, July 31, 2026

FridayreportedcommonwealthDay 4 of 28

A morning jury view of the Duxbury house, the CVS and the restaurant, then a half sitting of hospital evidence: two custody officers whose cross-examinations built the defense's suicide-attempt record, two emergency physicians the defense did not cross at all, and the toxicology chain of custody.

Key points
  • THE DAY'S BEST DEFENSE EVIDENCE CAME OUT OF COMMONWEALTH WITNESSES. Neither custody officer was a defense witness, and between them Reddington's cross-examinations put in front of the jury the full-width neck laceration, the slices across both wrists, blood inside and outside the clothing cut off her, blood below the window and on the sill, ledge and shingles, a bloodied knife on the nightstand, and a middle-of-the-night code that Lippard agreed meant she was dead or dying. On the defense theory that she intended to kill herself, this is the corroboration, and it is in the Commonwealth's own case.
  • Maffeo conceded on redirect that nobody at South Shore was treating the cuts to her neck and wrists while he was there. Boston 25 and East Idaho News both record it; NBC10 describes the same point being pressed on cross.
  • CAUTION ON THE CODE BLUE. On direct Lippard said only that there was some kind of medical code during the night and that he was not sure what it was. The phrase code blue, the approximate time of 2:24 a.m., the words chaos and bedlam, and the proposition that a code blue meant she was dead or dying were all put to him by Reddington on cross and agreed to. What the code actually was is not established by this testimony.
  • Lippard did not recall the defendant being handcuffed to the bed when asked whether she was chained to it.
  • LIMITS ON MAFFEO. He was at the house during the State Police search warrant but was not present when the pill bottles were seized and not present when the nightstand drawer was opened. The medication evidence therefore does not run through him.
  • Neither doctor was cross-examined, and neither was the laboratory supervisor. Three of the day's five witnesses left the stand unchallenged, consistent with a defense that does not contest the acts or the medical cause of death.
  • Arcadipane is the chain-of-custody link for the toxicology the case turns on: a preservation notice on the defendant's blood and urine on January 24, more than six vials of blood and one urine sample, collected by a state trooper with a warrant days later per boston.com. Boston 25 records only that she handed the samples to the State Police and does not date the collection.
  • Dr. Tenerowicz pronounced Dawson dead at 7:28 p.m., which East Idaho News renders as 19:28. This file previously logged that as a conflict with the case reference, which carries 19:28 as Cora's pronouncement by Dr. Snyder. The reference's own conflict notes now record it as resolved: two children were pronounced at the same hospital minutes apart, Dawson by Tenerowicz at 19:28 and Cora by Snyder at about 19:30. The reference's timeline and decedent fields have not been rewritten to match that note.
  • Old bruising on Dawson's legs is reported only by East Idaho News, from Tenerowicz's testimony. No other outlet mentions it and nothing was reported about where it came from.
  • HOW THE JURORS WERE SPLIT IS IN DISPUTE. East Idaho News, the Associated Press and Fox News describe three groups of six; the Boston Globe describes a jury of eighteen including six alternates taken through in groups of three. Every account agrees the whole visit ran about forty minutes.
  • The view was allowed over the objection of the current owner of the house, resolved at a pretrial hearing (Boston Globe). NBC10 reports Judge Sullivan telling the jurors that what they saw counted as evidence. Boston 25's legal analyst Elyse Hershon explained that counsel could point jurors at a feature but could not tell them what happened there.
  • The prosecution's use of the view is the timeline. Retired Superior Court judge Jack Lu told Fox News that a view is routine in a homicide case and that the value here was letting jurors measure the length of the husband's errand. CBS Boston's analyst Jennifer Roman framed it as letting jurors count the stairs between the basement and the second floor.
  • Reddington told WBZ-TV's Kristina Rex that the Commonwealth ran out of witnesses again on Friday and that he expects its case to finish earlier than scheduled. Judge Sullivan told the jury the trial was well on schedule if not ahead. This is counsel and the bench on pace, not a ruling.
  • SCHEDULING IS RECORDED TWO WAYS. Boston 25, boston.com and East Idaho News all have the jury back Monday at 9 a.m.; East Idaho News additionally records the judge saying he expected a late start on Monday with a full day of testimony. No outlet explains the two together.
  • NAME AND RANK. Reported as Marcanthony Maffeo by the Boston Globe, Boston 25, CBS Boston and boston.com, and as Mark Anthony Maffeo by East Idaho News, which matches the case reference. boston.com resolves the title: a detective on January 24, 2023, a sergeant by the time he testified.
  • East Idaho News numbers these witnesses fourteen through eighteen for the Commonwealth. This file's ordinal counts sitting days, not witnesses, and the two are not related.
  • No exhibit number was reported for any photograph, any item of clothing, or the medical records.
