A charge stemming from threats to disrupt July 4 fireworks displays last year in communities including Orland Park and Tinley Park has been dismissed by the Cook County state’s attorney’s office.

The charge of filing a false police report, a misdemeanor, was dismissed against 51-year-old Jeanette Larue of Tinley Park on June 27, according to the state’s attorney’s office, which declined to say why the charge was dropped.

Police throughout the Chicago area were on heightened alert regarding Fourth of July events after a gunman killed seven people and wounded dozens of others during an Independence Day parade last year in Highland Park.

Police allege that Larue sent a series of text messages to her nephew July 4 threatening to attack fireworks displays in Orland Park and neighboring Tinley Park as well as Lockport and Joliet.

Tinley Park police Chief Matt Walsh said he does not know why the charge was dismissed, and that his department did not find out until after the fact.

Police, at the time Larue was charged, said they were able to determine before the fireworks shows in Orland Park and Tinley Park that there was no danger to the public.

Tinley Park police said Larue’s nephew contacted them after receiving the text messages and that Larue admitted to sending the messages but denied sending any threatening messages.

Larue did not respond Tuesday for requests to comment.

Law enforcement agencies throughout the Chicago area were on alert to possible attacks to Fourth of July events last year after a man, later identified as 21-year old Bobby Crimo III, allegedly unleashed a hail of gunfire onto people watching a parade in Highland Park.

Some communities opted to cancel events but displays continued in southwest suburbs such as Orland Park and Tinley Park, with decisions coming after the suspected shooter was taken into custody and concerns about a possible broader threat discounted.
