A lunch fundraiser is being held tomorrow to benefit a Bossier City police officer's son. The Bossier Fraternal Order of Police Lodge 39 and Bossier City Police Local 645 are hosting the event, which runs from 11 to 1 tomorrow in front of the Bossier City Police Department. Grilled hamburgers, chips and drinks will be available for purchase to the public. The lunch benefits Tyson Warren, the 3-year-old son of Bossier City Police Sergeant Tyrone Warren. Doctors recently removed a malignant tumor from Tyson's brain, and he'll have to undergo further treatment at St. Jude Children's Research Hospital in Memphis, Tennessee. All the proceeds from the fundraiser will go toward treatment expenses.
