A high school student in Stockton died Monday after she was stabbed on campus, officials said.
The 15-year-old girl was stabbed several times at about 11 a.m. Monday at Stagg High School and died at a hospital, Stockton Unified School District Superintendent John Ramirez Jr. said at a news conference.
The girl's name wasn’t immediately released.
The girl was standing near the front of the school when a man pulled up, got out of a car, and attacked her.
"A trespasser entered the front of our school today and stabbed one of our students multiple times," Ramirez said in a news conference Monday afternoon. "Unfortunately, she did not make it."
The assailant attacked before security and staff could stop him, he said.
“We definitely will be re-evaluating” campus security, Ramirez said.
“Detectives believe this appears to be a random act and they are trying to determine why this student was targeted,” according to a statement from the Stockton Police Department.
Police arrested 52-year-old Anthony Gray.
