MIAMI (AP) - Miami police say someone fired a gun at a taxicab, killing a passenger and injuring the driver.

Det. William Moreno said the taxicab was stopped at a traffic light late Sunday when a second vehicle approached from behind and started shooting into the taxi.

A passenger, identified only as a man in his 40s, has been pronounced dead.

The driver of the taxicab is in critical condition.

A third person, described by police as an innocent bystander in a pickup truck across the street, was shot in the leg. Moreno said the injury was non-life threatening.

Authorities do not have a motive, and said it is too early to say whether the shooting was a random or targeted crime.

Anyone with information is asked to contact Crime Stoppers at 305-471-TIPS.
