No one was hurt, the police said.

The driver, who was identified as Michael Chadwick Fry, 34, was taken to a hospital for a “medical evaluation” and was later booked into the Dallas County Jail on a felony criminal mischief charge, the police said. No bond had been set as of Wednesday afternoon.

Major Max Geron of the Dallas Police Department said the man had “mental issues” and was trying to bring attention to the fatal shooting, which occurred in Denton County, north of Dallas. In that October 2012 episode, a Denton County sheriff’s deputy opened fire on a car Mr. Fry was riding in after the authorities said the driver, Roberto Hernandez, tried to ram into the deputy’s cruiser.

Mr. Hernandez was struck and killed, while Mr. Fry, who had jumped into the back seat, was not injured. Mr. Fry, who has a lengthy criminal record in Denton County, was charged with probation violation.

A video from the station on Wednesday showed the man removing paper from a duffel bag and from boxes in the back of the truck. He also stacked a pile of documents outside a door to the building. One of the documents was a copy of a news article about the Denton County shooting with mug shots of Mr. Hernandez and himself.

Notes had been written around the article. “They tryed to kill me. and they missed. and hit him,” the notes read. “They have been trying to killing me for years now.”
