OTTAWA – A text message scam purporting to be from a Sgt. John Peck of the LaSalle County Sheriff’s Office has been reported by some residents.    The Sheriff’s Office warned the public Saturday that they would not be calling or texting to demand money, even if you have a warrant out for your arrest.   The number the scammers provide in the message does not connect to the Sheriff’s Office.  Authorities advise to never give out personal details over the phone, especially to those demanding money or unusual payment methods.
