Authorities said two brothers were killed in a high-speed multi-vehicle crash around noon Tuesday on US 17-92 in Casselberry. The wreck happened near Sunnytown Road, with one report also placing it near SR-436.
The victims were identified as Christopher J. Marier, 42, and Tyler M. Marier, 40. Local reports said both men were in a gray SUV when it was hit. Authorities said the other driver was fleeing before the crash, and aerial tracking was used rather than a ground pursuit.
The collision was described as a deadly impact involving another vehicle traveling at a very high rate of speed. Beyond that, officials had not publicly released a full crash reconstruction in the information available, and many details about the sequence of events remained under investigation.
The crash happened along one of Casselberry's busiest corridors, and the area near Sunnytown Road drew immediate emergency response after the impact. No additional injury information was confirmed in the fact record beyond the two fatalities.
For families affected by a fatal crash like this one, official records can become important in the days ahead. That can include the traffic homicide or crash report, vehicle information, insurance correspondence, and any witness details or photos tied to the scene while authorities continue to review what happened on US 17-92 in Casselberry.
We are deeply saddened for the family and loved ones of those killed in this Casselberry crash.
