PORTLAND, Ore. (AP) — Murder charges against a man suspected in the deaths of two people have been dismissed after a Multnomah County judge found the man unfit to stand trial, prosecutors said Tuesday.

Demetrius Brown, 26, is at the Oregon State Hospital undergoing treatment for mental illness and will likely stay there, The Oregonian/OregonLive reported.

On Jan. 14, a Multnomah County Circuit Court judge issued an opinion and order finding Brown unfit and determining there is not a substantial probability that Brown, in the foreseeable future, will regain the capacity to stand trial, prosecutors said.

Brown was the suspect in two murders, an attempted murder, an assault and witness tampering, and prosecutors said he was involved in another shooting that resulted in the death of a pregnant woman. In January 2018, he was sent to the state hospital.

Under Oregon law, a person can only be held for three years while receiving treatment and waiting for trial. That term was up last month.

Brown is being held at the state hospital under Oregon’s “extremely dangerous person with mental illness” law, and a review board will hold a hearing to determine the best placement for him.

If Brown regains competency to stand trial, the state can and may reconvene the grand jury and re-indict Brown on the murder charges, prosecutors said.
