Aug. 28 (UPI) — In Minneapolis, people of all faiths have united in mourning after Wednesday’s church school shooting that killed two children.

Minneapolis officials have added another victim to the total from yesterday’s mass shooting at the Church of the Annunciation.

Current totals now are two children, ages 8 and 19, who were killed by shooter Robin Westman, who died by gun suicide at the scene, according to Minneapolis officials.

Another 15 children and minors between ages 6 and 15 were injured, along with three adult parishioners who were attending the morning school mass at the church in south Minneapolis.

Hundreds of people gathered at Lynnhurst Park in the city on Wednesday evening to mourn the two children who were killed. Many left flowers and candles.

A memorial prayer was held at the Academy of Holy Angels at 8:58 p.m. after starting late to accommodate hundreds of attendees, the Star Tribune reported.

“I was very moved to see how many churches were having prayer services this evening, how many of our Protestant brothers and sisters [attended],” Archbishop Bernard Hebda told those in attendance.

“I received messages today from the Jewish community, from the Muslim community,” Hebda added. “I know there are representatives from both of those groups who are here.”

Hebda read a message from Pope Leo, as written by Cardinal Pietro Parolin.

“He sends his heartfelt condolences and the assurance of spiritual closeness to all those affected by this terrible tragedy,” Hebda said.

The Minneapolis Police Department increased its patrols near the school, and city officials are coordinating with the St. Paul Police Department, Hennepin County Sheriff’s Office and other local law enforcement to provide added security at all schools in the city’s metro area for the next couple of weeks.

A news conference was scheduled at 1 p.m. CDT at Minneapolis City Hall and was to include local officials, law enforcement and members of Everytown for Gun Safety, Moms Demand Action and Students Demand Action.

Westman, 23, legally purchased the rifle, shotgun and pistol used to carry out the attack at the religious school for children in pre-K through eighth grade.

Westman once attended the Annunciation Catholic School, and Westman’s mother formerly was a teacher.

Westman was born Robert Westman but, according to Fox News, changed his name to Robin in 2019. CNN reported that Westman graduated from Annunciation’s grade school in 2017, based on a yearbook photo.

Local officials say Westman acted alone, and local police obtained four search warrants for the church and three other locations in Minneapolis, which led to the recovery of several more firearms.

A motive remains unknown, but Westman had posted a manifesto online, along with photos of firearms and ammunition magazines upon which he had written various statements.

The online content has been removed, and the FBI is investigating the shooting as an act of domestic terrorism and a hate crime against Catholics, FBI Director Kash Patel said in a post on X.
