A man nicknamed “Betinho” strolled so nonchalantly down the aisle in a Brazilian church behind a bride and groom that everyone thought he was a part of the ceremony—until he pulled out a gun and opened fire at three guests.

New York Daily News reports that Umberto Ferreira dos Santos, AKA “Betinho,” was reportedly targeting a father and son attending the wedding at the Our Lady of Conception church in the centre of Limoeira de Anadia.  Police reports claim the attack was out of vengeance for the death of his own son. Video footage caught the entire ordeal, as what looked like a peaceful and happy wedding, turned into a nightmare.

As gunshot fires rang through the church, guests screamed, scattered, and ran for their lives, but apparently Betinho wasn’t interested in harming anyone except Cicero Barbosa da Silva, 62, his son Edmilson Bezerra da Silva, 37, and Edmilson’s wife, sitting beside the father and son. All three were shot as point blank range after the suspect accused them of hurting his son. Afterwards, Betinho casually walked out of the church.

After the shooting and utter chaos, the bride and groom, determined to get married, finished out the ceremony.

A guest at the wedding, who wants to remain anonymous, told a local reporter that no one really understood the motive or why someone chose a wedding to open fire.

“We have no idea what is the motive of this attempted murder, nor why it was done precisely during the wedding, as the victims walked around the town freely and any time of the day or night.”

All three suspect survived the shooting and are undergoing surgery. Brazilian police are still searching for the suspect.
