3 arraigned in Southampton Street stabbing

BOSTON, Mass. (WLNE) — Suffolk County District Attorney Kevin Hayden said that three people were arraigned for their role in a triple stabbing on Southampton Street last week.

Jaden Mathieu and Juan Shanks, both from Dorchester, as well as Mikia Steed are all accused of being involved in a large brawl at the Southhampton Street Shelter on July 15.

Hayden said that video footage at the shelter showed Mathieu approach Shanks and strike him over the head with a firearm.

The firearm was then dropped and picked up by Jose Alicea, who brought it to a tent. Hayden said police confiscated the firearm and that Alicea was not charged.

The two men then wrestle with each other on the ground, before Shanks is stabbed in the back by an unknown suspect in a dark colored hoodie and red pants.

Hayden said that Steed is then shown to punch, kick, and hit Shanks with a milk crate, before she is stabbed in the back after Shanks gets up and chases her.

During the fight an unknown suspect wearing a green t-shirt and blue jean shorts is seen approaching the scene wielding a machete, which is confiscated by security guards.

Both Shanks and Steed were transported to local area hospitals, while Mathieu went to Boston Medical Center himself with a stab wound.

Mathieu, who is 20-years-old, was charged with assault and battery with a dangerous weapon, carrying a firearm without a license, and possession of ammunition without an FID card.

Shanks, who is 33-years-old, was charged with armed assault to murder and assault and battery with a dangerous weapon.

Steed, who is 38-years-old, was charged with two counts of assault and battery with a dangerous weapon.

Hayden said both Mathieu and Shanks were deemed dangerous and were ordered to be held, while Steed had bail set at $2,500 and was issued a stay away and no contact order with the other defendants.

Mathieu will return to court on for a dangerousness hearing on July 26.

Shanks has a probable cause hearing on Aug. 25

Steed, meanwhile, has a pre-trial hearing on Aug. 18. She also has an open warrant in Suffolk Superior Court for a masked armed robbery that occurred in December 2022.

Hayden added that the suspect in a dark colored hoodie as well as the suspect in the green t-shirt have not yet been identified.
