In early September, the attacker identified himself in a court filing as Jeremiah Farmer, and wrote that he had "physically beaten Mr. Kelly in a [sic] attempt to shed media spotlight" on his own case.
An employee identified as "D. Szyhowski" was attempting to meet with Farmer "when he left the office against my (Szyhowski's) order to stay," according to a Federal Bureau of Prisons incident report attached to the September filing.
Szyhowski wrote he observed Farmer head into an "out of bounds" section that wasn't his when he heard a disturbance coming from a nearby cell. Farmer appeared to be on top of Kelly, Szyhowski wrote, "punching inmate Kelly repeatedly in the head and torso."
