MIAMI (AP) — A boat collision off the Florida Keys has left one woman dead and injured another.

The Coast Guard said in a news release that a 44-foot Catamaran and 55-foot sport-fishing boat collided Thursday afternoon near Mud Key, ejecting both women from the sailboat into the water.

The women were brought by helicopter to Lower Keys Medical Center in Key West. One was declared dead and the other was reported in stable condition. The Coast Guard did not release their names, ages or hometowns.

The Florida Fish and Wildlife Conservation Commission is investigating the collision.
