Two teens killed in a car crash in Miami

South Florida police say two teens involved in a car crash and a good Samaritan who stopped to help them were killed when another vehicle plowed into them.

Miami-Dade Police Detective Alvaro Zabaleta said the teens' car collided with an SUV, driven by Josefa Quinones, 68, early Sunday in an intersection. The teens got out of their car, and they were joined by a man who stopped to help.

Zabaleta said a red Kia Forte, driven by 30-year-old Christopher Masferrer, drove into the scene, hitting all three pedestrians and crashing into the SUV.
