A 19-year-old man, accused of tossing an explosive through a broken window of the downtown Portland federal courthouse in July and injuring a deputy U.S. marshal, was killed Sunday in Portland, according to a source with knowledge of the matter.

Isaiah Jason Maza Jr. was fatally stabbed in the 100 block of Northeast 120th Avenue, according to the source [....] Officers were called to the scene about 5:30 p.m. and found Maza dead.

In August, Maza appeared in the Mark O. Hatfield United States Courthouse on allegations of assault on a federal officer using a dangerous weapon and depredation of federal government property.

Assistant U.S. Attorney Gary Sussman described Maza as a “very dangerous man” who was caught on video tearing plywood off the window. He is then seen lighting the fuse, dropping the hand-sized explosive device inside the lobby of the courthouse “then watching with his cellphone for the explosion.”

At the time of the July 22 incident, Maza was on pretrial release from a state first-degree criminal mischief charge. That charge was still pending at the time of his death.

Assistant Federal Public Defender Susan Russell at the time said Maza was working on credits to complete his high school diploma after having previously attended Rosemary Anderson High School. He was living with his mother, had a 2-year-old child and worked at Home Depot. She told the court he was undergoing counseling for post traumatic stress and anxiety [....]
