LOS ANGELES — A man with a semiautomatic rifle opened fire at a church festival Saturday, wounding his ex-wife and two bystanders before festivalgoers grabbed him and held him for police, authorities and a church official said.

Witnesses described a chaotic scene, with people screaming and running for the exit after gunfire rang out on a grassy field where the festival was being set up at the St. John Baptist de la Salle Roman Catholic parish.

Fernando Diaz Jr., 33, was arrested on suspicion of attempted murder, said Los Angeles Police Officer Ana Aguirre. He was held in Van Nuys jail in lieu of $1.5 million bail.

"I don't really have too much to say about that. It's a personal thing between me and the church," Diaz said to a KNX-AM reporter before being taken to jail.

When asked if he has an issue with the church, Diaz responded: "The church has an issue with me."

Diaz's 29-year-old wife was wounded in the arm and a 45-year-old man was wounded in the leg. Both were hospitalized in stable condition. A 43-year-old man was hit in the chest and was hospitalized in critical condition.

The victim's names were not released.

"We believe this is an isolated incident, a domestic-violence dispute," said police Capt. Steven Ruiz.

Diaz has a child who attends the church school and has had an ongoing custody dispute with the mother, Ruiz said. Authorities said Diaz was on parole for an unspecified crime, and a restraining order was in place to prevent him from being near the school, his son and wife.

The church's pastor, Father Robert Milbauer, said the festival was about 10 minutes from opening and about 50 volunteers, some accompanied by their children, were busy setting up food and game booths and carnival-style rides when the gunfire began.

McKINNEY, Texas — School officials say they are appalled by altered photos — including heads on different bodies — in hundreds of McKinney High School yearbooks delivered this week.Besides the head and body switching, some necks were stretched, one girl's arm was missing, and another girl's head was placed on what appeared to be a nude body, with the chest blurred.A spokeswoman for Minnesota-based Lifetouch National School Studios Inc. said the alterations were "an unfortunate lapse in judgment" by an employee but didn't believe it was malicious.The high school had required Lifetouch to make heads the same size and eyes at the same level in all student photos, company spokeswoman Sara Thurin Rollin said Saturday. The request was "unusual and definitely very particular, but that's not to suggest what happened here is acceptable," she said.Rollin declined to say if the company fired or reprimanded the employee who altered the images. She said Lifetouch is taking full responsibility for the altered pictures, about 30 in all, and will pay to have the publication reprinted before the seniors graduate.Lori Oglesbee, the school's yearbook adviser at McKinney High School, said the yearbook staff would spend the weekend rebuilding the yearbook.McKinney is about 20 miles north of Dallas.
