Officer Safety alert:
Another Career Violent Repeat Offender...
On 12/11/09 a 911 call was received by our department. The caller, Adam M. Pierson (MW, 02/19/76, KS D/L: K01-74-4754, 6'3", 250#), threatened to shoot four police officers in the head. It was learned that Pierson was upset after being warned about panhandling in Vernon Hills a short time earlier. Pierson was found and arrested at his apartment later in the day. However, only Class A Misdemeanor was approved and Pierson was bonded out by his girlfriend, Teresa M. Grandinetti (FW, 12/16/63). Both reside at 5227 N. Reserve Avenue, Apartment 1W, Chicago.
After leaving LPD, Pierson stopped at the Shell gas station in Lincolnshire to buy cigarettes. While inside he began telling shoppers and employees that he was going to kill two Lincolnshire Officers tonight and that they could watch it all over the news tomorrow.
With the assistance of the Norridge Police Department, Pierson was stopped and arrested within one hour. During the second interview he admitted to the threats, but told Investigators the threats were not specific to Lincolnshire Officers.
A felony was approved after the second incident and he is being held at the Lake County Jail on $20,000 bond. It is doubtful he will post bond at this time, but please post this for officer safety.
Pierson has many prior arrests for violent crimes across the country (FBI #376616XA8). He drives a blue-green 1993 Ford Taurus station wagon, Kansas Registration 275BGZ. His girlfriend drives a red 1991 Buick, Illinois Registration 9149316. If you have any questions, please contact Investigator Anderson or Investigator Hyde at 847-883-9900.
