Boston Police continue to investigate a stabbing incident in Mattapan Square around 4 a.m. on Jan. 4 in the wake of a report suggesting that the assault stemmed from an after-hours gathering inside a commercial property next to a parking lot where a man was found with multiple wounds to his neck and head.

A BPD report on the incident obtained by The Reporter laid out the following account:

Officers called to the scene on Cummins Highway found a crowd of people exiting an alley shared by the commercial building and a supermarket. The victim was lying on the sidewalk surrounded by bystanders applying pressure to a neck wound. The officers provided aid until an ambulance arrived and EMTs transported him to a Boston hospital. There has been no recent update on the man’s condition.

Officers then followed a trail of blood to the back door of 1651 Blue Hill Ave., which was locked, but a second nearby door was open, and officers entered the premises, where they interviewed a man with blood on his clothing and on a flashlight as well who told them that “a realtor had given the keys to a party promoter and allowed him to throw parties in the basement.”

Officers told the man to unlock the door to 1651 Blue Hill Ave. While a search inside found no one inside that space, officers noted that the bloody trail continued from the back door and into the basement. The scene was frozen for further investigation.
The Reporter contacted Inspectional Services Department (ISD) last week, which has a special task force focused on after-hours party activity, but has received no response to date.

Last September, a few blocks away, police busted up an illegal nightclub in the basement of a home at 24 Rexford Rd, where they found more than 50 people inside with all the outside doors padlocked. Inside was a fully stocked bar, multiple hookahs, and a DJ booth. Two men were arrested for illegal firearms during the encounter.

In an unrelated Mattapan incident on Monday morning this week, two men were found stabbed outside Macumba Latina at 477 River St. near the Square, shortly after 2 a.m. Universal Hub reported that the homicide unit was called to the scene due to the severity of one of the victim’s injuries; however, no deaths have been reported.

The club was the scene of a stabbing last August that left one person with non-life-threatening injuries. Two men were arrested and charged in that incident. The business was also the subject of a license review following a 2023 shooting that left two people injured.
