Police have arrested three people in the investigation of this week's mass shooting in Sacramento, California, which left six people dead and a dozen more wounded, officials said Tuesday.
Detectives "identified a man who was seen carrying a gun in the immediate aftermath of the shooting" before they later "recovered a handgun and arrested" Daviyonne Dawson, 31, Sacramento police said.
He was taken into custody late Monday and booked on suspicion of being a prohibited person in possession of a firearm.
"At this time, Dawson is not charged with crimes directly related to the shootings," police said in a statement Tuesday afternoon. "Based on the type of firearm recovered, detectives do not believe that this gun was used in the shooting. Detectives are continuing to investigate this crime and identify additional suspects."
He is the brother of Dandrae Martin, the first suspect taken into custody, authorities said, and he remains under guard at a hospital.
Smiley Martin was "located at the scene with serious injuries from gunfire" and taken to the hospital, where he was "quickly identified as a person of interest," police said in a statement.
Once Smiley Martin is well enough to leave the hospital, he will be booked into jail on suspicion of possession of a firearm by a prohibited person and possession of a machine gun, police said.
Prosecutors last year fought to keep Smiley Martin in prison, calling him a danger to the community, Sacramento County Deputy District Attorney Danielle Abildgaard wrote in a letter obtained Tuesday by NBC News.
"Inmate Martin has committed several felony violations and clearly has little regard for human life and the law," Abildgaard wrote in an April 29, 2021, statement to the parole board.
Abildgaard pleaded with the board, saying, "Martin should not be released as he poses a significant, unreasonable risk of safety to the community."
He was released last summer after having spent three years in prison, nowhere close to a 10-year sentence, for domestic violence.
The first person to be arrested, Smiley Martin's sibling, Dandrae Martin, 26, was taken into custody early Monday and booked on assault and illegal firearm possession charges, police said.
The mass shooting occurred in the bustling downtown area near 10th and K Streets shortly after last call early Sunday. Investigators believe multiple shooters opened fire in the wake of a large fight that spilled into the streets and covered several city blocks.
None of the people who have been arrested has been formally accused of homicide. Police said detectives are actively working the case and interviewing witnesses.
"As these processes occur, different and/or additional charges may apply," police said. "The Sacramento County District Attorney’s Office will be reviewing all evidence to determine appropriate charges."
Mayor Darrell Steinberg thanked police for their fast work, saying in a statement early Tuesday that investigators moved to "so methodically and quickly to apprehend suspects in this horrific shooting."
It wasn't immediately clear whether the men had hired or been assigned defense lawyers by Tuesday morning.
Dandrae Martin was being held without bail in the Sacramento County Main Jail, according to sheriff's records. He was scheduled to be in court Tuesday afternoon, records showed.
The Sacramento County coroner on Monday identified the three men and the three women who were killed as Johntaya Alexander, 21; Melinda Davis, 57; Yamile Martinez-Andrade, 21; Sergio Harris, 38; Joshua Hoye-Lucchesi, 32; and DeVazia Turner, 29.
