A UA student who went to high school with the man who fired a shot at a restaurant early Saturday morning said yesterday that the gunman and the victim were friends.

Jacob Ochoa, liberal arts freshman, was arrested on two charges of aggravated assault after the shooting, and could face expulsion from the UA.

Officials say Ochoa did not live on campus and did not have a permit for the gun he had the night of the incident.

Ochoa shot Jordan Prather at No Anchovies, 870 E. University Blvd., Saturday after Ochoa was wrestled to the ground by two men whom he had accused of taking his seat.

Retail and consumer science sophomore Gina Giachetti said she went to Catalina Foothills High School with both Ochoa and Prather and was friends with them.

The two men who Ochoa first approached reportedly wrestled Ochoa to the ground after he became angry and lifted up his shirt to show them his handgun.

Prather was thought to have been helping hold Ochoa down and was shot during the scuffle.

Prather's injury was not life-threatening, said Tucson Police Department spokeswoman Michelle Pickrom.

Giachetti said Prather and Ochoa may have been at the restaurant together and thought the shooting was probably a weird coincidence.

"I was shocked," she said. "I had been hanging out with (Ochoa) the night before."

Giachetti said she would never have expected Ochoa to be involved in a situation like this.

Pickrom said there was nothing in the initial police report to indicate that Ochoa and Prather were friends.

Ochoa did not have a concealed weapons permit for the gun he used to shoot Prather with, Pickrom said.

UA Administrative Associate of Residence Life Felicia Hermann said Ochoa was not in their records and does not live on campus.

Ochoa has been released from Pima County Jail and could possibly face disciplinary action from the UA.

UA Associate Dean of Students Veda Kowalski could not comment on Ochoa's particular case, but said students involved in violent activity could face expulsion depending on the incident.

Kowalski said UA administration takes action in student cases involving sale or distribution of drugs, gambling and violence that present a danger to others.

"Anyone can make a complaint about a student and we follow up using the student code of conduct," she said.

Kowalski said the investigation gives the student an opportunity to address the allegations while the administration interviews witnesses and reviews the case.

Disciplinary action could range from a warning to expulsion, she said.

Kowalski said students brought before the administration because of violence that presents a danger are more likely to be expelled than students with gambling or drug-related allegations.

Kowalski said the time it takes to get from a complaint to expulsion depends on the complexity of the case and the time of year.

Allyn Smith, chemistry junior, said he was in the area the night the shooting occurred.

"We were driving around campus and saw cops," he said. "We didn't know what was happening and when we asked, everyone in the car was just shocked, you know."

Smith said he thinks Ochoa should be expelled for the shooting.
