A Washington man was arrested on Wednesday after Seattle police said he shot his 9-month-old son in the head while under the influence of a hallucinogenic drug.

Dion Lamont Montgomery, 35, faces several charges, including first-degree murder, in connection to the death of his son, according to an affidavit obtained by HuffPost.

Police responded to a report of shooting at around 6:30 p.m. on Wednesday, the Seattle Police Department said in a statement that night.

Witnesses told officers that Montgomery had fired four to five shots at two people before running off, according to the affidavit, though neither bystander was injured.
