ARIZONA SLAYINGS Students: Man was angry, mean

Officials said the Gulf War veteran killed himself after shooting three nursing school instructors.
TUCSON, Ariz. (AP) -- Robert Stewart Flores Jr. struggled as a nursing student at the University of Arizona. Classmates said he tangled with instructors and annoyed fellow students.
"He came across as very aggressive and mean and seemed to have a lot of issues with being angry," said Lori Schenkel, a fellow nursing student.
Authorities said Flores' anger boiled over Monday when he reportedly shot three of his professors to death during a rampage at the College of Nursing that sent dozens of terrified students diving for cover.
Officials said the 41-year-old Gulf War veteran had been carrying five handguns and at least 200 rounds of ammunition. After shooting the three staff members, Flores turned one of the guns on himself.
"Mr. Flores went in there to create a holy hell for our community," Tucson Police Chief Richard Miranda said. "I can't imagine what the building would look like if he didn't have a sudden change of mind."
No explosives found
Bomb squad members were called in after a backpack or package was found underneath the gunman's body. The suspect had threatened to blow up the building, though it was unclear when the threat was made, police said. The college and nearby buildings were evacuated but no explosives were found.
Police said Flores first killed professor Robin Rogers, 50, in her office on the second floor of the nursing school building. He then went to the fourth floor, where he entered a classroom full of students taking a test being given by two teachers.
There he confronted Cheryl McGaffic, a 44-year-old ethics teacher who studied the relationship between health and spiritually in seriously ill patients.
He told McGaffic "he was going to give her a lesson in spirituality," said student Laura Kelley. Witnesses said Flores fired two shots into McGaffic's chest and stood directly over her as he shot her in the head.
Barbara Monroe, 45, was reportedly Flores' last target. The instructor was cowering behind a desk as Flores approached, witnesses said. "He asked her if she was ready to meet her maker. She said 'Yes,' and then he shot her once and then twice more," said student Gena Johnson.
Flores worked at the Veterans Administration hospital in Tucson as a licensed practical nurse and was studying to become a registered nurse.
Failed class
Flores failed a pediatric nursing class and was struggling in a critical-care class this term, said University Vice Provost Elizabeth Irvin.
Schenkel said Flores bragged to pediatrics classmates last year that he had received a concealed weapons permit. She said he seemed to enjoy calling attention to himself by asking inappropriate questions and challenging instructors. He failed that class and had to take it again, Schenkel said.
"Most of the people in class didn't like him," Schenkel said. "He was very obnoxious and rude."
