A suspect has been sentenced to five years in prison after he committed arson at a billionaire family’s home in Highland Park and then threatened to kidnap their daughter if they did not provide him $80,000 in cash. They are one of two known billionaire families who reside in Highland Park. A day later, an unknown number sent text messages to the family’s daughter with the same information that was sent to the wife. The FBI coordinated with the Highland Park Police Department to use technology and warrants to isolate the sender. Katris said law enforcement identified that the text messages were sent from the Highland Park Public Library.
