Four high school students and two other people were shot in Las Vegas Tuesday as the students were exiting a school bus.
Police believe the shooting stemmed from an altercation earlier in the day at Mohave High School.
One after another, the young shooting victims were brought here to UMC's trauma center.
Some of the victims were alert and talking as they arrived but one of them, according to paramedics, suffered a critical gunshot to the stomach area.
Police are convinced the shootings were not a random act of violence.
Marc Joseph of the Las Vegas Police Department says the shooters were waiting for certain individuals on the bus.
Witness Elaine Budesa says, "they were just sitting ducks. As soon as the bus pulled away, bam bam bam."
Evidence gathered here at the scene indicates two guns were used.
Police found shell casings from a 45-calibur handgun and a 9-mm.
Numerous teens were questioned and Metro's helicopter scanned the area for any sign of the attackers. Police are still looking at gang-involvement or even a love-triangle as a possible motive for the crime.
