Authorities are investigating a shooting that took place at the Church of Jesus Christ of Latter-day Saints in Fallon, Nevada. At least one person was killed and one person was injured Sunday afternoon, according to CBS affiliate KTVN-TV. The station writes that the suspect, John K. O'Connor, 48, is in custody but has not been charged yet.

KTVN-TV reports there were about 50 witnesses when the incident unfolded inside the church. Police say the suspect went home after opening fire and police followed him there where a hostage negotiator was able to get him to surrender.

O'Connor is a member of the church and had been attending services prior to Sunday's incident.

Officials tell KTVN-TV that the suspect was targeting individuals, not the church. A motive was not immediately made clear. One of the victims suffered a non-life-threatening gunshot wound to the leg.

The victim who died has been identified as Charles E. Miller, known to everyone in the city as "Burt," according to a press release.

A spokesperson for the Mormon church said, "We express our love to those in this congregation and our prayers for the victims and their families. Local leaders are ministering to them at this time."

Nevada Sen. Dean Heller wrote on Twitter that he's "deeply saddened by the act of senseless violence in Fallon today."
