San Antonio police say a violent confrontation between two drivers ended in the deaths of two adults and two children in a West Side wreck.
Police said the incident occurred just before 6 p.m. at the intersection of Culebra Road and Pettus.
Investigators said the wreck stemmed from an apparent confrontation between two drivers. They said one driver pulled out a handgun and threatened the other driver.
A San Antonio police patrol officer, who happened to be in the area, saw the confrontation and tried to intervene, going so far as to pull his police vehicle between the two drivers.
Investigators said the suspect, who has not been identified other than police saying he is a 31-year-old man, tried to ram the officer's vehicle, before fleeing the scene in a gray Toyota Corolla. The officer pursued the suspect down Culebra for several blocks.
They say the suspect sped off, but crashed into a another vehicle -- a white Chevrolet sedan -- containing two adults and three children.
The two adults and two of the children died in the wreck. Their names, ages and genders have not been released.
The third child was taken to an area hospital in critical condition.
The suspect and an unidentified passenger in the suspect's vehicle were also taken to an area hospital in unknown condition.
Police investigators recovered a handgun at the scene that is believed to belong to the suspect.
It is not yet known what charges the suspect will face, but police did confirm that he has been arrested.
