The woman yelled out, "Help! He's trying to kill me!"
A witness and several construction workers in the area chased Kuchta and were able to hold him down until police arrived to arrest him.
"I heard the screaming for help and just the tone of it, the volume of it, you could tell this was something pretty serious," construction worker Kris Weller said.
According to investigation documents, "Kuchta appeared high on narcotics" and "admitted he had just injected meth before the assault."
"The look in his eyes, you could tell he was on something," Weller said.
Kuchta's criminal history includes a 2009 attempted murder charge in Oregon when he was a juvenile.
His current address listed in the SPD incident report is a homeless shelter in Pioneer Square.
In May, in Tacoma Municipal Court, Kuchta was charged with two misdemeanor assaults and obstruction of a public servant in May 2019. Kuchta was released on his own recognizance. When he failed to appear at his next court hearing, a warrant was issued for his arrest.
In July, Kuchta was arrested on a bench warrant and entered pleas of guilty to one count of fourth-degree assault on Aug 1.
Kuchta was given a 364-day suspended sentence and released from the Pierce County Jail on the same date, according to his most recent charging documents.
Four days later, Kuchta allegedly attacked the woman in Ballard with the pitchfork.
Kuchta has been in the King County Jail since his arrest on Aug. 5. His bail was originally set at $75,000 but was raised to $150,000 because of "the alarming acts of random violence displayed by the defendant in this case and the defendant's history of violence," according to court documents.
