According to authorities, Preston at 1:40 a.m. Saturday was found near her home by a fellow officer who had responded to a call of shots fired in the 8100 block of South Blackstone Avenue. Preston, who had recently gotten off work, was rushed from a squad car to the University of Chicago Medical Center where she succumbed to her wounds, officials said.
Mayor Lori Lightfoot said during a press conference early Saturday that she spoke with the officer's family, who is "completely shattered."
"I won't speak for her mother," Lightfoot said, "but I can tell you that she poured everything she could into her child. No mother wants to wake up to the tragic news their child is dead and to something as awful and tragic as gunfire."
Lightfoot said she directed Interim Chicago Police Supt. Eric Carter to "spare no expense to make sure we find the people responsible for this and bring them to justice."
Mayor-elect Brandon Johnson issued the following statement Saturday morning:
"This is a profound tragedy, and my heart breaks for the family of the young officer who was murdered early this morning on her way home from work. I’m outraged and devastated by this horrific violence against a public servant, and I will do everything I can to support her family and the Chicago Police Department through this traumatic time. I pray that her killer is apprehended quickly so that justice may be served."
