Angered by a 78-year-old woman's comments about the rap song he was listening to, Victor Brancaccio, 16, bludgeoned her to death with a cassette player, police said.
Mollie Mae Frazier was taking her routine walk about 6:30 p.m. Friday when she was killed. The incident occurred about 200 yards from Brancaccio's home in a quiet, upper-income suburb, said Theresa Woodson, spokeswoman for the Port St. Lucie Police Department.
The day after the crime, Brancaccio tried to burn Frazier's body in an attempt to remove fingerprints by crumpling newspaper and lighting it. But he succeeded only in burning her shorts and part of a leg, said Martin County Medical Examiner Frederick Hobin.
Brancaccio then spray painted the body a metallic red to remove remaining fingerprints, Hobin said.
Brancaccio told friends he beat and kicked Frazier to death and left her body in a vacant lot near his home after she complained that his music contained obscenities, police said. One of the friends then told police.
Assistant State Attorney David Morgan said his office may prosecute Brancaccio as an adult because of the nature of the crime.
