Florida teen stabbed to death by 'homeless drifter,' police say

Ryan Rogers was stabbed to death in November, police said.

Investigators arrested a homeless man in Miami, who, they said, was responsible for the homicide of a 14-year-old boy in Palm Beach Gardens, Florida.

Police said they took Semmie Lee Williams Jr., a 39-year-old "homeless drifter," into custody on Wednesday night on the charge of stabbing Ryan Rogers to death on Nov. 15.

According to an affidavit, Rogers' autopsy revealed that he had been stabbed numerous times in the head and face and his cause of death was stab wounds.

DNA evidence from a pair of headphones found near Rogers' body was entered into a database and provided a positive match to Williams, police said.
