Three charged with assaulting Suffolk County correctional officers
BOSTON, July 16, 2026 – Three Suffolk County inmates are facing charges for their roles in an attack that left two officers injured in the Suffolk House of Correction last month, Suffolk District Attorney Kevin Hayden announced.
TONY MOSLEY-JOSEPH, 37, and JAHSAN MIEREZ, 18, were both arraigned in Roxbury BMC Tuesday on two counts of assault and battery on a correctional facility employee and one count of disturbing a correctional institution.
Mierez is currently being held without bail for a pending firearm-related case out of Roxbury BMC.
Mosely-Joseph is being held without bail for a pending assault and battery on a family or household member case out of Dorchester BMC.
Judge Dana Pierce ordered Mosley-Jospeh held on $500 bail and ordered Mierez held on $250 bail on the new charges. They will both return to court on September 14 for pre-trial hearings.
JACQUES LESSLY, 43, will be arraigned on September 14 in Roxbury BMC for one count of assault and battery on a correctional facility employee and one count of disturbing a correctional institution.
Lessly has several open cases, including a possession of a class B substance with intent to distribute case out of Suffolk Superior.
On June 14, a correctional officer reported that, at around 3:35 p.m., inmate Jahsan Mierez became “verbally disruptive and threatened to knock [the officer] out.” Mierez then stood up from his seat, approached the officer, and threw multiple closed-fisted punches to the officer’s head and body. An officer nearby attempted to stop the altercation and in doing so was hit by multiple closed-fisted punches in his head and body as well.
While officers attempted to restrain Mierez, another inmate, later identified as Mosley-Joseph, threw multiple closed-fisted punches to the head and body of both officers. Mosley-Joseph then wrapped his arm around the first officer’s neck while Lessly threw additional closed-fisted punches to the officer’s head and body.
Officers were able to restrain and identify all parties involved and transported them to segregation.
Following the incident, the first officer was treated in the Suffolk County Sheriff’s Department Infirmary and was later transferred to a local hospital for further treatment. The officer sustained injuries to his head, shoulder, and lower back.
The second officer sustained injuries to his knee, back, hand, and head.
“This set of facts points out how unpredictable any shift can be for a correctional officer. I commend these officers for bringing this violent episode to an end in quick order and I wish them a full and fast recovery,” Hayden said.
All charged individuals are presumed innocent until and unless proven guilty beyond a reasonable doubt.
