"The safety and security of Postal Service employees and customers is core to the mission of the Postal Inspection Service," says Ruth M. Mendona, Inspector in Charge of the Chicago Division of the U.S. Postal Inspection Service. "There is no place for this type of senseless violence. 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. This arrest is the first step in securing justice for Mrs. Redmond. We hope this brings the Redmond family some semblance of relief. As our investigation continues, we maintain our call to the public to come forward with any information that may continue to bring those responsible to justice."
