One person was killed and four others were wounded when a gunman opened fire at a church on Sunday, authorities said.

The Orange County Sheriff's Department said one person had been taken into custody, but it didn't release the person's identity. Authorities also said they had collected a weapon believed to be involved in the shooting, which took place at the Geneva Presbyterian Church in Laguna Woods. The shooting, which occurred around 1:30 p.m., comes one day after an 18-year-old white male traveled "hours" to conduct a mass shooting at a grocery store in a predominantly black neighborhood of Buffalo, New York.

Officials said a fifth person also suffered minor injuries. Each victim was an adult.

The Laguna Woods area that the gunman targeted in Sunday's attack has numerous houses of worship, including Catholic, Lutheran, and Methodist churches, as well as a Jewish synagogue.

The Buffalo attack on Saturday left 10 dead and three seriously wounded. That suspect, Payton Gendron, is expected to face hate crime and first-degree murder charges.

"I know you all have questions about what this was about, and I'm going to be honest with you: We are not there yet," Milwaukee Assistant Police Chief Nicole Waldner said in the immediate aftermath of the carnage, adding that her department needed "time to investigate."
