Officials say three people were shot Thursday afternoon at South Mountain Community College in Phoenix.

The Phoenix Police Department said the shooting took place in the computing commons of the Technology Center building located at the southern end of the campus.

It took place around 4 p.m. when officers said the suspect walked into the computer lab and picked a fight with the 19-year-old victim. Police said it appears the men have a long-standing feud.

“This was not a random act against the school or a classroom,” said Phoenix Det. Reuben Gonzales.

After shooting the victim, the suspect then shot a 20 year-old female and a 17-year-old boy before leaving the area, police and witnesses said.

All three victims were transported to the Maricopa County Medical Center where the female and boy were listed in stable condition. The 19-year-old male is in critical condition.

The names of the victims are unavailable, but Jay Taylor, of Phoenix, said his younger brother Christopher is the 17-year-old victim.
