Four people were killed and three others critically injured when a Mazda Miata and taxi collided early Saturday morning in Pasadena. The driver of the sports car lost control turning from Kirby Boulevard onto East NASA Parkway around 1:30 a.m., veering into oncoming traffic and hitting a minivan taxi cab that was carrying four tourists in town to take a cruise out of Galveston, according to Pasadena Police Department spokesman Vance Mitchell.
