The Washington man accused of shooting and killing a person and injuring another inside a grocery store on Monday has been arrested, police said.

Aaron Christopher Kelly, 39, was taken into custody without incident and is being held at Benton County Jail, where he faces charges including first-degree murder and attempted murder, the Richland Police Department announced in a social media post.

"We thank the numerous law enforcement partners that quickly collaborated to apprehend this subject," the police department added in the post.
