Sacramento police arrested a third suspect in their investigation of the deadly mass shooting downtown early Sunday morning.

Investigators have not, however, charged Daviyonne Dawson with anything directly related to the shooting, NBC News reported.

Dawson “was seen carrying a gun in the immediate aftermath of the shooting” and later “recovered a handgun and arrested” him, police said.

He’s been charged with being a prohibited person in possession of a firearm.

“Based on the type of firearm recovered, detectives do not believe that this gun was used in the shooting,” police said. “Detectives are continuing to investigate this crime and identify additional suspects.”

Six people were killed when gunfire broke out at about 2 a.m. Sunday as bars in the area were letting out. Another 12 people were wounded.

One of the wounded — 27-year-old Smiley Martin — was arrested and charged with possession of a machine gun and possession of a firearm by a prohibited person, as CrimeOnline previously reported. His brother, 26-year-old Dandrae Martin, was arrested Monday on charges of assault with a firearm and being a prohibited person in possession of a firearm.
