CHICAGO (WTVO) — Josiah Brown, the 3-year-old boy who was pushed off Navy Pier last week by his aunt, has died, according to the Cook County Medical Examiner.

A suburban Chicago woman faces felony charges after she allegedly shoved the boy into Lake Michigan and did nothing to save the boy, who was rescued by firefighters, officials said.

Victoria Moreno, 34, of Des Plaines, Illinois, was charged with attempted first-degree murder and aggravated battery to a child under the age of 13 causing permanent disability, police said Wednesday.

Cook County Circuit Court Judge Susanna Ortiz denied bail for Moreno during a Wednesday bond hearing, despite defense arguments that she suffers from mental issues. Ortiz called Moreno’s alleged actions “intentionally brutal and heinous,” the Chicago Sun-Times reported.

Prosecutors said Wednesday that 3-year-old Josiah Brown was pushed Monday afternoon into Lake Michigan by his “beloved aunt” who then stood by as he sank to the lake bottom off Chicago’s Navy Pier, where divers found him a half-hour later.

The boy went into cardiac arrest and was rushed to Lurie Children’s Hospital in “very critical condition,” officials said.
