LOS ANGELES – Authorities on Monday said a deadly shooting at a Southern California church was a “politically motivated hate incident” against the Taiwanese community.

At least one person was killed and five people were injured when the shooter opened fire Sunday afternoon at the Geneva Presbyterian Church in Laguna Woods, which was hosting a Taiwanese congregation. 

The Orange County Sherriff’s Department on Monday identified the suspect as David Chou, 68, of Las Vegas. Chou was booked on one felony count of murder and five felony counts of attempted murder, the sheriff’s department said in a tweet.

The Federal Bureau of Investigation has also opened a hate crime investigation into the shooting.

Authorities said Chou drove to the church Sunday morning and entered during a luncheon, opening fire on a group of largely elderly congregants. Chou secured the doors of the church with chains and attempted to disable the door’s locks with superglue, according to Orange County Sheriff Don Barnes.

Police also discovered several bags around the church containing magazines of ammunition as well as Molotov cocktails, Barnes said Monday.

Chou, a Chinese immigrant, targeted the church in an “isolated incident” because of frustration over political disagreements between China and Taiwan, Barnes said. It is not clear why the specific church was targeted.

Police identified the victim who died as John Cheng, a congregant at the church who was shot after charging the suspect and attempting to disarm him. His “heroic actions” allowed other individuals to subdue the suspect and hogtie the suspect’s legs with an extension cord and take away his weapons, Barnes said. 

Cheng was pronounced dead on the scene.

“Dr. Cheng is a hero in this incident,” Barnes added. “Without the actions of Dr. Cheng, it is no doubt that there have been numerous additional victims in this crime.”

How did the Laguna Woods church shooting unfold?

Police said the shooter was armed with two handguns when he entered the church around 1:30 p.m. PT Sunday. 

About 50 people inside, most of whom were of Taiwanese descent, had just finished morning services and were gathering for an afternoon luncheon following a morning church service, officials said. They ranged in age from 66 to 92 years old, according to Barnes.
