A stolen firearm used in the mass shooting in Sacramento on Sunday has been converted for use on a fully automatic weapon, police said.
Authorities did not release further details about the weapon. But it is possible to convert a handgun into an automatic weapon that can fire like a machine gun.
It was suspected that an automatic weapon was used in the shooting because video of the incident recorded rapid fire. When the gunfire ended, 18 people had been injured, six of them fatally.
Authorities estimate that at least 100 shots were fired.
Investigators obtained a social media post released Saturday by a suspect, Smiley Martin, in which he brandished the stolen weapon, according to law enforcement sources.
This post has since been deleted. The Times has not independently reviewed the message.
A second suspect, Martin’s brother, Dandre Martin, 26, was arrested early Monday on suspicion of assault with a firearm and being a felon in possession of a firearm. He will be incarcerated in the Sacramento County Jail on suspicion of “prohibitive person possession of a firearm and possession of a submachine gun” as soon as his medical treatment is complete, police said.
In a statement, police said Smiley Martin, 27, was among those seriously injured in the shooting early Sunday and remains hospitalized in custody.
Videos have emerged of the shooting in downtown Sacramento that underscore the chaos of the situation.
One shows a large group of people fighting in the street, followed by rapid gunfire. another catch several volleys of gunfire, including what looks like a possible automatic weapon, before people on the street run for their lives.
Sacramento police said they believe a scuffle could have triggered the gunfire, but are unsure what sparked the conflict.
Witness Alexandra Arellano said she was about to leave a club where she worked when she heard a gunshot, then “about 30 or 50 bullets fired”.
Arellano’s fiancé, Jesse Fuentes, said he and another security guard heard a commotion at a nearby garage. “Once we got there it was pretty much a shootout,” he said. “We were just trying to take cover because we couldn’t tell where the shots were coming from at first because they were coming from two different areas. But the one that really freaked everyone out was the guns. This is when everyone was running and pushing.
