Massachusetts — In a tragic case of escalating violence at a Massachusetts park, 25-year-old Dayana Slade and 35-year-old Michael Thompson are now at the center of an investigation into a fatal altercation that left Mike Jonas dead after a confrontation at Finnegan Park on September 23, 2025. The shooting and subsequent events have sparked a massive law enforcement effort, culminating in the couple’s arrest after nearly six months on the run.
The incident, which began with an accusation of disrespect, ended in the brutal death of Jonas and the near-fatal injury of another man involved in the fight. Following the murder, both Slade and Thompson evaded capture, leaving authorities to piece together a complex series of events while searching for the couple. Their apprehension in Lewiston, Maine, on March 5, 2026, brought an end to the manhunt, but questions regarding the altercation, the couple’s motives, and the aftermath remain in the spotlight.
The Incident at Finnegan Park
It was a warm afternoon at Finnegan Park in Massachusetts when the confrontation that would turn deadly occurred. Dayana Slade and Michael Thompson had been spending time at the park when Slade allegedly approached her boyfriend with a complaint: a man at the park had disrespected her. According to Slade’s statements to Thompson, she wanted him to “do something about it.” Thompson, upset by his girlfriend’s account, took matters into his own hands.
Slade, according to witnesses, remained in their Nissan Rogue parked nearby, while Thompson confronted the man, later identified as Mike Jonas. The two began a conversation, which quickly escalated into an altercation. The confrontation spiraled out of control, drawing in at least two other individuals, turning the incident into a violent brawl. What began as a dispute between two men soon involved multiple people, as Thompson and Jonas reportedly exchanged heated words before the fight became physical.
Escalating Violence: Mike Jonas Shot and Stabbed
During the brawl, Thompson allegedly pulled out a firearm, and shots rang out. Mike Jonas was struck multiple times by gunfire and also stabbed, according to police reports. The violence was brutal, and despite attempts to stabilize him, Jonas went into cardiac arrest and was pronounced dead shortly after the incident.
In the chaotic aftermath, another individual involved in the fight was also shot but survived, though their identity has not been publicly released. Witnesses describe the scene as chaotic, with several people scrambling to escape the violence as law enforcement was contacted.
Thompson’s Return: Bloodied and Upset
After the fight, Michael Thompson reportedly returned to the Nissan Rogue, bloodied, crying, and upset by the events that had unfolded. He then allegedly instructed Slade to “drive away immediately”, as he appeared to be in shock and unable to process what had just happened. In a panic, the couple fled the scene.
Instead of heading directly home, Slade dropped Thompson off at his residence in Dorchester, Massachusetts. After this, Slade drove the Nissan Rogue to her mother’s home in Weymouth, where she abandoned the vehicle. According to investigators, both Slade and Thompson discarded their phones during this time, making it harder for law enforcement to track their movements after the incident.
The Discovery of the Vehicle: Forensic Evidence Left Behind
A few days after the fatal shooting, police discovered the vehicle in Weymouth. Inside, authorities found several key pieces of evidence, including multiple firearms, which were believed to have been in Thompson’s possession at the time of the shooting. Investigators also recovered a sweatshirt that was reportedly worn by Thompson during the altercation, as well as spent shell casings matching those found at the scene of the fight.
Forensic analysis of the vehicle and its contents led investigators to the conclusion that Thompson had been involved in the shooting, while also pointing to Slade’s role in helping him evade capture. With these critical clues, investigators were able to connect the couple to the crime.
The Manhunt: Six Months on the Run
After the shooting, Slade and Thompson went into hiding, and for nearly six months, local, state, and federal authorities worked tirelessly to locate the couple. The FBI, along with Massachusetts State Police and the U.S. Marshals Fugitive Task Force, launched an extensive search for the pair, canvassing the surrounding states and working with local police departments to gather leads.
The couple’s ability to evade capture for an extended period raised significant questions. Investigators suggested that Slade and Thompson may have traveled to different states, possibly hiding out in areas where they believed they could remain undetected.
In the months following the shooting, law enforcement issued multiple press releases, requesting the public’s help in locating the couple. Rewards were offered for information leading to their arrest, and the FBI’s most wanted list featured their names, urging anyone who knew their whereabouts to come forward.
The Arrest in Lewiston, Maine
On March 5, 2026, after nearly six months of searching, authorities apprehended Dayana Slade and Michael Thompson in a second‑floor apartment in Lewiston, Maine. The arrest followed tips from the public, and investigators worked with local police to track down the couple to a relatively isolated area.
When law enforcement officers executed the arrest, they found both Slade and Thompson in the apartment. At the time of their arrest, both individuals appeared to have been living under assumed identities. It’s still unclear whether the couple had been in Maine the entire time or had moved between states since the shooting.
Local authorities and the FBI were able to capture the couple without incident, and they were taken into custody. Slade and Thompson were transported back to Massachusetts to face charges related to the shooting death of Mike Jonas and the subsequent fleeing of the scene.
Court Status: What’s Next for the Couple?
As of now, the court status for Michael Thompson and Dayana Slade is as follows:
-
Michael Thompson is being held without bond as he faces charges including murder, armed robbery, assault, and fleeing the scene of a crime. He is expected to appear in court for a pretrial hearing later this month.
-
Dayana Slade was granted bond set at $250,000 and is currently facing charges of accessory to murder, assisting a fugitive, and obstruction of justice. Slade has pleaded not guilty to the charges, as has Thompson.
-
Both Slade and Thompson have entered not guilty pleas and are expected to stand trial for the murder of Mike Jonas and related offenses. Their next court appearance is scheduled for February 26, 2026.
The Legal Process: What’s at Stake
The prosecution will likely focus on proving the connection between Thompson’s actions and the shooting death of Mike Jonas. Given the forensic evidence linking Thompson to the scene — including the recovered firearms, blood evidence, and the sweatshirt — authorities are confident in their case against him. The fact that Jonas was shot multiple times and also stabbed makes the case particularly complex, as the severity of the violence will play a key role in determining the charges, potential sentencing, and motive.
As for Dayana Slade, her role in the altercation is under close examination. While she did not directly participate in the physical confrontation, investigators believe that she was actively complicit in helping Thompson evade capture after the shooting. She allegedly drove the getaway car, discarded evidence, and helped hide Thompson from authorities, making her an accessory after the fact.
Both Slade and Thompson face serious prison time if convicted, with Thompson’s charges carrying the potential for life imprisonment or even the death penalty in certain circumstances.
The Impact of the Tragedy
The tragic events at Finnegan Park in Massachusetts have devastated not only the families involved but also the local community. Mike Jonas’s family and friends have expressed shock and sorrow over the loss of a man whose life was taken so suddenly and violently.
Jonas, described as a hardworking individual with a kind heart, was well‑known to those in the park community. His family has since issued a statement, mourning the loss of a loved one and hoping that justice is served.
Additionally, the incident has raised important questions about anger, relationships, and escalation. What began as a verbal confrontation turned into a senseless act of violence that ended in the loss of life.

Reflection on Violence and Accountability
As the trial approaches, the case will likely spark broader discussions about domestic violence, escalating conflicts, and the consequences of reacting to perceived disrespect with extreme violence.
