Casselberry driver faces life sentence after crash killed two brothers
Two brothers were killed on U.S. Highway 17-92 in Casselberry, and prosecutors filed second-degree murder charges that could put Marquavious Tayvon Wheaton in prison for life.
The Seminole County State Attorney’s Office filed two counts of second-degree murder against Marquavious Tayvon Wheaton, 26, after a fiery Casselberry crash killed brothers Christopher J. Marier, 42, and Tyler M. Marier, 40. News 6 said the charge exposed Wheaton to a possible life sentence, and WESH reported that he was held without bond after his first court appearance.
FOX 35 Orlando identified the Marier brothers as the victims and said they were killed on U.S. Highway 17-92 in Casselberry on July 7. The deaths turned a roadway collision into a homicide case in Seminole County, where court records also listed two counts of third-degree felony murder, two counts of vehicular homicide, and fleeing or attempting to elude a law enforcement officer.
Investigators said Wheaton fled after a traffic stop around noon Tuesday before causing the crash along U.S. Highway 17-92, and WFTV described him as a suspected fentanyl trafficker. Deputies did not start a ground pursuit, citing public safety concerns, a decision that now sits alongside the murder charges as prosecutors build the case.
The legal exposure in the case goes well beyond a traffic citation or a routine crash investigation. With two deaths, the State Attorney’s Office moved the case into the most serious tier of criminal court, and the possibility of a life sentence underscores how quickly a violent crash on one of Seminole County’s busiest corridors can become a prosecution for murder.
For the Marier family, the loss is permanent. For Casselberry, the crash on U.S. Highway 17-92 has become a reminder that dangerous driving can leave behind both shattered families and a court case that will follow the defendant for years. Wheaton remained held without bond as the homicide case moved forward in Seminole County.
