A Portland-based attorney was sentenced Wednesday to 18 months in prison for firing several bullets into the Beaverton office of another lawyer.

Erik Graeff, 43, pleaded guilty in October to unlawful use of a weapon and recklessly endangering another person, according to court records. He was convicted of both charges Wednesday, while another unlawful use of a weapon charge was dismissed.

He’s now in Oregon Department of Corrections custody, according to the Washington County District Attorney’s Office.

Graeff also faces charges in Washington after police found evidence he was creating methamphetamine in his Vancouver home. That case remains open.

Prosecutors in the Oregon case said Graeff fired six rounds from a handgun into the offices of a Beaverton law firm in December 2017.

No one was hurt, but a bullet nearly hit an employee inside, court records show. The shooting came after an argument between Graeff and an attorney at the law office, according to the records. The attorney was upset about Graeff's work on a case they had teamed up on. Graeff disagreed he was at fault.

Graeff was also sentenced Wednesday to two years of post-prison supervision, records show. He will have to participate in mental health and alcohol treatment programs and pay the victims $5,000, prosecutors said.

An Oregon State Bar spokeswoman Thursday afternoon said the bar suspended his license to practice in the state Jan. 15 pending the outcome of a disciplinary hearing.
