Brockton Man Arrested Following Double Stabbing on White Avenue
BROCKTON, MA — A 34-year-old Brockton resident is currently in police custody and facing severe felony charges after a violent altercation left two men suffering from stab wounds on Wednesday afternoon. The incident, which prompted a swift, multi-unit response from local law enforcement and emergency medical personnel, highlights ongoing concerns regarding violent crime in the region’s urban centers.

John Tamulevich, 34, of Brockton, has been formally charged with two counts of assault and battery with a dangerous weapon. The charges stem from a chaotic encounter that unfolded in a residential neighborhood, leaving two individuals requiring immediate medical intervention and prompting an ongoing investigation by local detectives.
The Incident on White Avenue
According to initial reports from the Brockton Police Department, dispatchers received emergency calls on Wednesday afternoon reporting a stabbing in progress. Uniformed patrol officers and emergency medical technicians (EMTs) were immediately routed to the vicinity of 24 White Avenue, a residential street situated within the city limits.
Upon arriving at the scene, first responders successfully secured the perimeter to ensure public safety and located two adult male victims who had sustained visible injuries consistent with stab wounds. Emergency medical personnel rapidly assessed the victims on-site, working to stabilize their conditions before preparing them for emergency transport.
Both men were subsequently transported by ambulance to a local hospital for further evaluation and advanced medical treatment. Authorities have officially classified their injuries as non-life-threatening, though the specific nature, severity, and exact anatomical locations of their wounds have not been publicly disclosed at this time. The identities of the two victims are currently being withheld by authorities, pending further investigation and adherence to standard medical privacy protocols.
Arrest and Legal Ramifications
Tamulevich was identified as the primary suspect in the double stabbing and was taken into police custody. The specific operational details leading up to his apprehension—including whether he remained at the crime scene or was located nearby during a subsequent police search—have not yet been detailed by the authorities.
Under Massachusetts General Laws, a charge of assault and battery with a dangerous weapon is a serious felony offense. If convicted, a defendant can face significant state prison time, making it a high-stakes case for the Plymouth County District Attorney’s office, which handles prosecutions for major crimes committed within Brockton. While the classification of the “dangerous weapon” used in this specific incident was not explicitly named in the initial press release, the resulting injuries indicate a bladed instrument was utilized during the assault.
Tamulevich is expected to be arraigned in Brockton District Court, where formal charges will be read before a judge, a plea will be entered, and bail conditions will be established.
Ongoing Investigation Procedures
Detectives assigned to the Brockton Police Department have officially taken over the investigation. As is standard procedure in incidents involving serious bodily harm, crime scene investigators were dispatched to the White Avenue location. Their primary objectives include:
- Collecting physical and forensic evidence from the scene of the altercation.
- Photographing the area to document the environment where the assault occurred.
- Canvassing the surrounding neighborhood to locate potential eyewitnesses.
- Securing residential and commercial security footage, including doorbell cameras, to piece together a definitive timeline of the encounter.
Law enforcement officials have not yet released any information regarding a potential motive for the double stabbing. It remains unclear at this stage of the investigation whether the suspect and the victims were previously acquainted, or if this was an isolated, random act of violence.
Regional Impact
