WATCH: Procession for deputy US marshal killed in Tucson

TUCSON, AZ (Tucson News Now) - Thousands mourned the loss of deputy U.S. marshal Chase White, Friday, Dec. 7.

A celebration of life for White, who was killed in the line of duty in Tucson last week, was held at the Tucson Convention Center.

Before the public celebration, a procession was held from a funeral home in Oro Valley to the TCC.

White, 41, was fatally shot while serving a warrant at a home in midtown on Thursday, Nov. 29. He is the first deputy U.S. marshal killed on duty in Tucson in 66 years.

Authorities arrested Ryan Schlesinger, 26, following a short standoff at the home. He is facing a charge of first-degree murder of a federal officer.

According to the warrant, Schlesinger had been stalking a sergeant in the Tucson Police Department.

Tucson police, including the sergeant who he allegedly stalked, had previous contact with Schlesinger on November 2017, while serving a petition for a court-ordered mental health evaluation. While there, Schlesinger allegedly threatened to kill officers and reached for a loaded handgun. Police used a stun gun and Schlesinger was taken into custody.

In April 2018, Schlesinger began emailing the TPD demanding the return of his handgun and other evidence taken during the incident. The emails allegedly contained threatening statements.

The complaint said Schlesinger made several appearances over a period of several months at the police department and a home belonging to the sergeant’s parents. He allegedly wanted to make a citizen’s arrests of police, including the sergeant, whom he confronted in person at the Miracle Mile station. That meeting was recorded on a body-worn camera.

In an online complaint filed by Schlesinger, he allegedly described a scenario in which he would be surrounded by TPD employees with their weapons drawn, and that he’d have no choice but to “render harmless the threats. ... I don’t think anybody wants this turning into shootout at the OK Corral."
