A 13-year-old boy who may have "idolized previous mass shooters" has been arrested after police found a large collection of guns and "mass shooting scenario" writings at his Washington state home, authorities said.

Police were notified on Friday afternoon about the boy, who allegedly had "school shooter ideations," "was making threats to kill" and said he had access to guns, according to the sheriff's office in Pierce County, which encompasses Tacoma.

Police searched the boy's home early Saturday morning. The sheriff's office said authorities found a "large quantity" of secured and unsecured guns; "loaded magazines with school shooter writings on them;" and clothes and writings that reinforce a "typical mass shooting scenario."
