A 35-year-old man from Massachusetts is facing charges for allegedly shooting and killing a 40-year-old man last year. This incident reportedly followed his girlfriend’s claim that the victim had disrespected her, prompting her to insist that he “do something about it.”

Authorities have announced that Michael Thompson was apprehended last week and is charged with first-degree murder in connection with the death of Mike Jonas.

Thompson’s girlfriend, 25-year-old Dayana Slade, has also been arrested related to the incident. She is charged with being an accessory after the fact in Jonas’ murder.

According to a statement from the Plymouth County District Attorney’s Office, the police responded to reports of multiple shootings at Finnegan Park around 4:15 p.m. on September 23, 2025. This location is near the intersection of Crescent Street and Montello Street in Brockton, roughly 20 miles south of Boston.

Upon arriving at the scene, first responders found two individuals with gunshot wounds. One victim, whose identity has not been disclosed, was taken to a nearby hospital with injuries that were not life-threatening. Despite paramedics’ efforts, the second victim, identified as Jonas, was pronounced dead on-site due to his injuries.

Prosecutors revealed that Jonas suffered from four gunshot wounds and multiple stab injuries during this deadly encounter.

Troopers with the Massachusetts State Police Detective Unit assigned to the district attorney’s office led the investigation into the shooting.

“Through preliminary investigation, law enforcement learned that an altercation occurred at Finnegan Park immediately prior to the shooting and were able to identify Thompson as the suspected shooter,” the release states. “The defendant was captured on surveillance footage leaving the area in a black Nissan Rogue while accompanied by two women, one of which was identified as Slade.”

Local police later located and seized the vehicle as part of the homicide investigation, but Thompson and Slade remained on the lam.  With assistance from the U.S. Marshals Service and local law enforcement, the fugitives were located and taken into custody in Lewiston, Maine, on Monday.

Thompson and Slade on Friday appeared for their arraignments in court, where prosecutors offered additional insight into the case. Plymouth County Assistant District Attorney Jeremy Kusmin told the court that the duo was at Finnegan Park when Slade told Thompson that a man — Jonas — had just disrespected her, adding that she “wanted him to do something about it,” according to a report from local news website The Enterprise.

While Slade stayed in the Nissan, Thompson allegedly returned to the park, where he confronted Jonas about the interaction with Slade. A physical altercation reportedly involving at least four people ensued and gunshots rang out a short while later, witnesses told investigators.

“When Mr. Thompson came back to the car, he purportedly was upset, might have been crying, and was covered in blood,” Kusmin reportedly said during the hearing. “He immediately got into the passenger seat and told Ms. Slade to drive.”

The couple then left the car at Slade’s mother’s home — leaving an alleged “arsenal” of firearms and other weapons inside the vehicle — before getting rid of their cellphones and leaving the state.

The mother of Jonas’ three children told authorities that the 40-year-old victim did not even know that one of his kids was expecting their first child when he died, per The Enterprise.

Thompson is being held without bond while a judge set Slade’s bond at $250,000. Both have pleaded not guilty to the charges against them. They are currently scheduled to appear in court again for a probable cause hearing on Feb. 26.
