With profound sadness, family members, friends, and members of the Casselberry community are mourning the tragic loss of Christopher J. Marier, 42, and Tyler M. Marier, 40, who lost their lives following a heartbreaking crash on U.S. Highway 17-92 near Sunnytown Road on Tuesday afternoon, July 7, 2026, in Casselberry, Florida.
The sudden loss of Christopher and Tyler has left loved ones devastated as they struggle to process a tragedy that took two lives far too soon. Their passing has brought deep sorrow to their family, friends, and everyone who knew and cared for them.
According to authorities, Christopher and Tyler were traveling in a gray SUV when their vehicle was struck near Sunnytown Road. Police said the crash involved a black sedan driven by 26-year-old Marquavious Tayvon Wheaton, and both men were pronounced dead at the scene.
Investigators said the collision occurred shortly after the Seminole County Sheriff’s Office attempted to stop Wheaton, who was suspected of trafficking fentanyl near 25th Street and State Road 417 in Sanford. Authorities said Wheaton failed to stop and fled, leading deputies to use aerial surveillance instead of a ground pursuit due to public safety concerns.
Officials said the suspect vehicle later traveled south on U.S. Highway 17-92 at speeds exceeding 100 mph before entering Casselberry. At approximately 12:04 p.m., the vehicle collided with the SUV carrying Christopher and Tyler.
While authorities continue investigating the circumstances surrounding the crash, those who knew Christopher and Tyler are remembering them for the lives they lived and the memories they created.
