Alfredo Emilio Villarreal

A Walworth County Sheriff’s Deputy shot and killed a jail inmate Monday evening at Aurora Lakeland Medical Center near Elkhorn as the inmate was attempting to escape, according to authorities.

Jail inmate Alfredo Emilio Villarreal, 18, of Janesville, was at the hospital for medical tests when, according to a sheriff’s office press release, he attacked the deputy.

Villarreal repeatedly punched and kicked the deputy in the face and then used a chair in an attempt to smash a window and escape.

When that failed, authorities contend Villarreal attempted to hit the deputy in the head with the chair at which point the deputy shot Villarreal.

He died at the scene.

Villarreal was incarcerated in Walworth County on a probation and parole hold from the state Department of Corrections.
