On December 13, 1984, Margaret "Peggy" Park, a 26-year-old wildlife officer, came across Grossman (then aged 19) and Thayne Taylor (aged 17) shooting a stolen handgun in a wooded area of Pinellas County, Florida. Grossman, who was on probation for grand theft and other charges after burglarizing a former girlfriend's house, asked her not to turn him in for possessing a weapon and being outside Pasco County. Both were violations of his probation.
