Second Suspect in Custody for 2025 Scarborough Homicide
Toronto Police have made significant progress in a homicide investigation from last fall, with a second suspect now in custody for a deadly shooting that occurred in Scarborough. The arrest comes months after the incident that claimed the life of 42-year-old Yueyuan Dong, a Woodbridge resident who succumbed to his injuries weeks after the attack.
Details of the Arrest and Ongoing Manhunt
Kye-Shawne Griffiths, 29, of Brampton, was arrested on Saturday, April 4, 2025, and charged with second-degree murder. This development follows the earlier surrender of Donald Keeshig, 29, of Toronto, who turned himself in to police at 42 Division in Scarborough on November 9, 2024, facing the same charge.
However, authorities continue their search for a third suspect, Kai Chen, now 30, of Markham, who remains wanted on a Canada-wide warrant for second-degree murder. Police have urged the public to come forward with any information regarding Chen's whereabouts or details about the murder.
Timeline of the Tragic Incident
The shooting occurred on September 24, 2025, around 10 p.m. near Sheppard Avenue East and Brimley Road in Scarborough. According to police allegations, the victim and suspects had attended an establishment together before becoming involved in a physical confrontation. The situation escalated when suspects brandished a firearm and shot Dong.
First responders performed life-saving measures at the scene, and Dong was transported to hospital by emergency run. Despite medical intervention, he died from his injuries on October 19, 2025, nearly three weeks after the shooting.
Police Investigation and Public Appeal
Toronto Police initially identified three suspects in late October 2025: Kai Chen, Donald Keeshig, and Kye-Shawne Griffiths. All were subjects of Canada-wide warrants at that time. With two suspects now in custody, the investigation continues as authorities work to locate Chen.
Anyone with information is encouraged to contact the Homicide Unit at 416-808-7400 or Crime Stoppers anonymously at 1-800-222-TIPS (8477). The case highlights ongoing efforts by Toronto Police to address violent crime in the city.
The arrests represent a crucial step in seeking justice for Dong's family, though the search for the remaining suspect underscores the challenges investigators face in resolving complex homicide cases.
