(CNN) -- For more than two decades, New Jersey investigators had not been able to solve the homicide of 5-year-old Timothy Wiltsey. His mother, Michelle Lodzinski, reported the boy missing on May 25, 1991, telling police he disappeared at a carnival. On Wednesday, 23 years after Timmy vanished, Lodzinski was arrested in Florida on a murder charge in connection with his death. His disappearance shook the South Amboy, New Jersey, community where his family lived. Dozens of volunteers searched nearby fields and marshes for clues, according to CNN affiliate WCBS. The case gained national attention after missing posters for the boy were distributed to thousands of rail employees in 13 states, WCBS reported. Timmy's picture was even displayed on a giant screen at Yankee Stadium.
