A man reportedly lashed out with a knife during hymn-singing at New Mexico's St. Jude Thaddeus Catholic Church in Albuquerque on Sunday, said USA Today, injuring at least four people.
Authorities on Monday filed formal charges against 24-year-old suspect Lawrence Capener, who stands accused of three counts of aggravated battery, reported USA Today.
St. Jude's Father John Daniel told local reporters Capener "was not in his right mind," according to Portland's WCSH.
The man was subdued after suddenly attacking congregants in the middle of 11 o'clock Sunday mass, witnesses said.
Church choir pianist Brenda Baca King told the local KRQE-TV about the moments leading up to the attack.
"I just remember seeing him hurdle over the pews, hurdle over people and run [toward] us and I thought, 'Oh my God, this is not good,'" she said, reported USA Today.
Valerie Schalow, who said she was sitting close to Capener during the service, told reporters: "He brought his hand up and just started stabbing him and stabbing him," according to WCSH.
Two of those hurt are in critical condition, reported CNN. Here's a video report on the incident:
