Portland, OR – On June 25, 2025, Multnomah County Judge Chanpone Sinlapasai convicted Jacob Abel Ramos, 45, of the following:
5 Counts of Unlawfully Manufacturing, Importing or Transferring a Firearm
6 Counts of Attempted Manufacturing, Importing or Transferring a Firearm
10 Counts of Felon in Possession of a Firearm
1 Count of Unlawful Possession of a Short-Barreled Rifle
In 2022 the Portland Police Bureau Central Precinct NRT investigated a prolific graffiti artist with the tag name of BIER. While executing a search warrant at Jacob Ramos’ residence, as part of this investigation, officers found ten total firearms – five of which were serialized and five appeared to be homemade. Of those firearms, one was largely 3D printed and one was later determined to be a homemade short-barreled AR-15 style rifle. Evidence at Ramos’ residence revealed a gun manufacturing workshop consisting of a 3D printer, specialized jigs, drills, raw components and scrap materials that were used to print and mill several of the functioning, non-serialized, polymer and metal firearms. During their search officers found body armor, a large quantity of ammunition, and many magazines and other firearm accessories. Other evidence relating to the still open graffiti allegations was also seized as part of this search warrant.
DDA Andrew MacMillan prosecuted this case for the state. The Multnomah County District Attorney’s Office would like to thank Portland Police Bureau Officers Nathan Kirby-Glatkowski and Amelia Flohr for their meticulous investigation of this case as well as DA Investigator Colby Panter for his diligent work and firearm knowledge.
