Florida drifter allegedly murdered 14-year-old boy in ‘completely random’ attack, police say

A homeless drifter is accused of killing a 14-year-old Florida boy whose body was found on a boulevard near an Interstate overpass a day after he disappeared.

Police arrested Semmie Lee Williams, 39, on Dec. 1, and he is being held without bond on a charge of first-degree murder with a weapon in connection to the fatal stabbing of Ryan Rogers in Palm Beach Gardens. Williams was previously being involuntarily held at a hospital after he was deemed to be a danger to himself or others.

On the night of Nov. 15, Rogers was last seen alive leaving his home on a bike around 6:30 p.m., according to the Palm Beach Post.

The Miami Herald reported Williams’ DNA was allegedly found at the crime scene and videos posted to the homeless man’s YouTube channel show him in the Palm Beach Gardens area when police believe Rogers, a high school freshman, was murdered.

“The incident itself appears to be a completely random act – we do not have a motive in this case,” Palm Beach Gardens Police Chief Clinton Shannon said. “[It was] an innocent child victim having a chance encounter with a very violent criminal.”

According to the publication, the YouTube channel also was instrumental in detectives tracking down Williams to Miami-Dade County.

The murder suspect's YouTube videos are reportedly a bizarre collection of conspiracy theories, ramblings and street scenes.

“They have chips planted all over my body right and they reading my mind through my ears and they be tearing up my shoes,” a voice can be heard commenting in one video. “For the past 10 years, every city I go to, the police they hit me with electric weapons to give me cancer.”

Williams could face the death penalty if convicted of the charge against him.
