Four people were killed, including three Cape Coral residents, after a three-car crash in Lehigh Acres Sunday morning.

A 22-year-old woman, 23-year-old man and 24-year-old man from Cape Coral were killed, as was a 25-year-old man from Palm Springs.

The four fatalities occurred when the sedan in which they were riding failed to negotiate a right curve while heading westbound on Lee Boulevard and traveled over a raised median into oncoming traffic heading eastbound. The vehicle collided with another sedan that was traveling eastbound. The four who died included the driver. One passenger in the westbound vehicle — a 20-year-old woman — survived and was taken to Gulf Coast Medical Center with critical injuries.

Two Lehigh Acres residents who were in the other sedan that collided with the vehicle in the deadly crash, were transported to Gulf Coast Medical Center with serious injuries.

That vehicle also collided with a third vehicle driven by a 24-year-old man who was also heading eastbound on Lee Boulevard. The driver of that sedan was taken to Lehigh Regional Medical Center with minor injuries.

The crash took place at approximately 11:40 a.m., according to Florida Highway Patrol.

The names of the deceased were not immediately released by the Florida Highway Patrol pending the notification of their next of kin.

The crash remains under investigation.
