CASSELBERRY, Fla. – The man accused of causing a crash that killed two brothers in Casselberry is out of the hospital and locked up in jail.

Marquaious Tayvon Wheaton, 26, is scheduled to appear in court on Friday.

According to a Seminole County Sheriff’s Office arrest affidavit, SCORE agents — the agency’s Collaborative Opioid Response Effort unit — were surveilling Wheaton’s black BMW on Tuesday because of his history of armed fentanyl trafficking. When an agent activated blue lights and a siren to pull him over on State Road 417, Wheaton sped away.

Deputies tracked the BMW as it drove on the wrong side of the road, passed cars on the shoulder, and ran red lights. The vehicle reached speeds over 110 miles per hour before the crash, the affidavit states.

The BMW slammed into the driver’s side of a brown Mazda at U.S. Highway 17-92 and Sunnytown Road. Brothers Christopher and Tyler Marier were inside. Both were pronounced dead at the scene, officials said.

Wheaton was pulled from the overturned BMW and transported to the hospital for treatment of minor injuries.

Court records show Wheaton was on felony probation at the time of the crash — convicted of robbery with a firearm and tampering with a witness in Seminole County. His criminal history dates back to 2016.

The Casselberry Police Department is continuing its traffic homicide investigation.

Wheaton faces nearly a dozen charges, including two counts of vehicular homicide, two counts of third-degree murder, and fleeing law enforcement. He is being held without bond.

Wheaton is set to face a judge at 2 p.m.
