The Independent reported that around one week ago a man who was fishing in the water off of Fort De Soto Park in Pinellas County reeled in the gun, which was inside of a plastic bag.
Dog The Bounty Hunter had searched that area for Laundrie, but Laundrie's remains were later found in Sarasota County, Florida.
Laundrie's remains were discovered on Wednesday, Oct. 20, at the T. Mabry Carlton, Jr. Memorial Reserve and Myakkahatchee Creek Environmental Park where law enforcement had been searching for him.
His parents had reported to authorities on Friday, Sept. 17, that they hadn't seen Laundrie in days.
Laundrie, age 23, was named a person of interest in the homicide of his 22-year-old fiancée, Gabby Petito, of Blue Point in Suffolk County.
Her remains were found in a Wyoming national park on Sunday, Sept. 19.
