A truck driver from Florida has been charged in connection with a crash in Frederick County that killed two people and left three others injured Monday afternoon.

Maryland State Police said that 34-year-old Watson Pierre of Sunrise, Florida, was driving a tractor-trailer on Route 75 in the Monrovia area of the county around 2 p.m. when the crash occurred.

The tractor-trailer, which was loaded with oranges, rounded a sharp curve at Ed McClain Road and overturned onto a pickup truck traveling in the opposite direction, police said.

Two people inside the pickup truck were killed in the crash. Their names have not been released. Another passenger in the pickup was flown to the University of Maryland Shock Trauma Center; his condition is unknown, police said.

A passenger in Pierre’s tractor trailer was transported to Frederick Memorial Hospital. His condition is also unknown, police said.

Pierre was flown to the shock trauma center and released after treatment. He was arrested Monday evening and taken to the Frederick County Detention Center to await a court appearance.

Pierre is charged with two counts of criminally negligent homicide and one count of failure to control speed to avoid a collision.

Investigators have not determined if the Pierre had been speeding. The speed limit in the area is 30 mph.

The investigation is ongoing, police said.
