Police have arrested a 15-year-old boy for the murder of a postal worker on Chicago’s South Side in July.

The boy, whose name has not been released, was arrested in Cedar Rapids, Iowa, WBBM reported.

Octavia Redmond, 48, was shot multiple times while delivering mail on July 19. She was rushed to Advocate Christ Medical Center in Oak Lawn, where she was pronounced dead.

Police released surveillance video of the shooting in August. That video showed the shooter getting into a stolen Dodge Durango before the shooting. A second video shows someone getting out of the Durango near the location of the shooting, running across the street and out of the camera view, then running back to the vehicle.

The vehicle was later found abandoned and torched.

“There is no place for this type of senseless violence,” Ruth M. Mendonça, Inspector in Charge of the Chicago Division of the U.S. Postal Inspection Service, said in a statement. “When members of our postal family are targeted, postal inspectors will not rest until justice is delivered on behalf of the victims, their families, and our postal community.”

Investigators have not indicated a motive for the murder.

The boy was quickly extradited back to Illinois and charged with first degree murder in Cook County Juvenile Court. He is being held in custody and will return to court on November 1.
