Black Lives Matter protesters crashed the wedding of a Sacramento police officer who was involved in a fatal officer shooting in March and posted a video of the incident.

The group of protesters tracked down the vineyard location of the wedding, which was about an hour outside Sacramento, by finding his wedding website and registry online. Hours before he was set to walk down the aisle, protesters stormed the room where he was getting ready and declared that he is a “murderer.”

Black Lives Matter Sacramento posted a video of the incident to their Facebook page, though we will not be linking to it as his identity is not meant to have been made public. The officer, who is black, was involved in the shooting of 22-year-old Stephon Clark — who had been holding a cellphone that the officer’s mistook for a gun.

During the wedding protest, a white demonstrator screamed at the officer demanding to know how he sleeps at night.

“I just wanted to know if you started planning your wedding before you killed Stephon Clark or after?” a woman shouts. “How you been sleeping since March 18? And I know this is supposed to be the happiest day of your life, he will not have that option.”

The protesters were eventually removed by the officer’s wedding party.

“I think they need to be approached in spaces where they’re a little more vulnerable,” Tanya Faison, founder of Black Lives Matter Sacramento, told CBS. “We’re not violent, we’re not gonna give to them what they brought to our community, we’re not gonna hurt anyone but we are gonna make them uncomfortable, and they should because someone is dead.”

Neither of the two officers involved in the shooting have been indicted.

The Sacramento Police Officers Association has defended the officer and spoke out about the protest.

“The SPOA supports transparency within our Police Department. Transparency brings trust. Trust between our officers and the citizens they protect is an important aspect of a safe community. Our police officers are members of this community. They raise their families here. The send their children to schools here. They live their lives as a part of this community,” the SPOA said in a statement. “Transparency comes with responsibility. Officers deserve to be free from harassment by individuals seeking their own forms of justice. True accountability can only come from our impartial judicial system and from our elected government.”
