From https://bpdnews.com/news/2023/6/22/update-to-death-investigation-at-381-old-colony-avenue-south-boston, 'The Official Website of the Boston Police Department'.
"There were four children on site who all had a parent present in the residence. The parents and the officers who responded felt it was best for the children to stay in another room with one of the parents and took steps to avoid having the children see the deceased."
And from https://www.nbcboston.com/news/local/4-kids-found-in-unsanitary-conditions-in-south-boston-apartment-authorities-say/3072622/
"Six adults who appeared to be men were in the apartment, fire officials said."
Parents, plural, all men, so fathers rather than mothers. Four children, from at least two families, aged from 5 to 10, apparently taken by their dads to a sex party.
From https://www.bostonherald.com/2023/06/23/boston-fire-union-blasts-mayor-wus-version-of-southie-od-den-call/
"The Fire Department reported finding the apartment “in extreme unsanitary conditions.” Firefighters found four children, ages 5-10, “in the back bedroom being hidden by an adult male from first responders.”
Further, the report states that the adults they encountered were uncooperative, and did not provide helpful information."
Which contrast somewhat with the police's "The adults on scene ... were fully cooperative with the Boston Police Officers who responded".
I'm going to go out on a limb here and suggest that those children require protection from their dads. And that the police are doing backflips to the sacred caste and possibly averting their eyes as no arrests have yet been made.
