A mother of three is dead after her vehicle was hit by a truck going the wrong way on a Connecticut highway.

On Sunday, Monica Wilson died of fatal injuries one day before her 42nd birthday, per an incident report from Connecticut State Police. An 8-year-old and 7-year-old were in the car with her and suffered minor injuries, police said.

Driving a 2019 Acura, Wilson and two other cars were heading south on Route 8 when a fourth car "traveling in the wrong direction" (going north) hit Wilson's car "head-on," the report says. As a result of their impact, "a chain reaction collision occurred" between the fourth car and the other two vehicles.

Wilson was taken to Bridgeport Hospital, where she died. The children with her have non-life-threatening injuries, according to the release.

The driver of the fourth vehicle, 35-year-old Wilber Martinez, suffered life-threatening injuries and is being treated at St. Vincent's Medical Center, where he "remains in critical condition." Martinez was driving a 2014 Ford E-150 that was not insured at the time of the collision, per the report.

His passenger, identified as Ananias Castillo-Icabalzeta, died at the scene.

The other drivers were taken to local hospitals and have non-life-threatening injuries.

The Connecticut State Police Collision Analysis and Reconstruction Squad (CARS) arrived at the scene, and Route 8 South was closed for about five hours. The incident is still being investigated.

Per Daily Voice, Wilson worked at Broad River Animal Hospital, which closed its doors on Monday to acknowledge her death.
