The firearm used in the Sacramento massacre was converted into an automatic weapon

A stolen firearm used in the mass shooting in Sacramento that killed six and wounded 12 on Sunday was converted to be used as a fully automatic weapon, reported the Los Angeles Times.

Authorities did not offer more details about the weapon. But it is possible to convert a handgun into an automatic weapon that can fire like a machine gun. 

There had been suspicion that an automatic weapon was used in the shooting because video of the incident recorded rapid fire. When the gunfire was over, 18 people had been wounded, six fatally.

Officials estimate at least 100 shots were fired.

Investigators have obtained a social media post made on Saturday by one suspect, Smiley Martin, in which he wields the stolen gun, according to law enforcement sources.

That post has since been removed. The Times didn’t independently review the post.

Sacramento police announced Martin’s arrest Tuesday. In a statement, they said Martin, 27, was among the seriously injured and remained hospitalized under police custody. He will be booked at the Sacramento County Jail on suspicion of “possession of a firearm by a prohibitive person and possession of a machine gun” as soon as his medical care is completed, police said.

Martin’s brother, Dandrae Martin — previously identified by police as Dandre Martin — was arrested early Monday. The 26 year old was booked on suspicion of assault with a firearm and being a felon in possession of a gun.

Videos have emerged of the shooting in downtown Sacramento that underscore the chaos of the situation.
