Authorities in California arrested a man who brought a cache of weapons, including gun paraphernalia, to a remote California abbey late last month.

Sheriff’s deputies arrested 38-year-old Joshua Michael Richardson after he allegedly made criminal threats against St. Michael’s Abbey, located in Silverado, about 40 miles southeast of Los Angeles in the Santa Ana Mountains.

Richardson, an Alabama resident, originally sent the abbey “emails that were interpreted as threatening,” the Orange County Sheriff’s Department said in a Sept. 2 press release.

The suspect subsequently “visited the church in person and made additional threats,” after which a priest reported the incident to the sheriff’s department.

Authorities quickly located and arrested Richardson for the alleged threats, and upon searching his vehicle they found “body armor, high-capacity magazines, brass knuckles, and knives.”

Richardson was booked into the Orange County Jail. Records show he is being held at a police facility in the city of Orange. 

In its press release the sheriff’s department urged residents: “If something seems off, say something.”

“Trust your instincts and report suspicious activity, whether it is a strange message, unusual behavior, or something that does not sit right,” they said. “Your call could stop a crime before it happens.”

St. Michael’s Abbey, run by the Norbertine Fathers in Silverado, was founded in 1961. Currently, 60 priests and more than 40 seminarians live there. The Norbertines of the abbey ran the nationally renowned St. Michael’s Preparatory School from 1961 to 2020.

News of the arrest comes roughly a week after a gunman perpetrated a mass shooting at Annunciation Catholic Church in Minneapolis, killing two children and injuring more than 20 other children and adults.
