WEST PALM BEACH — Semmie Lee Williams is headed to state prison for 35 years in the 2021 stabbing death of 14-year-old Ryan Rogers of Palm Beach Gardens.
Circuit Judge Cymonie Rowe sentenced Williams, 43, after a hearing that lasted an hour at the Palm Beach County Courthouse in West Palm Beach. During her sentencing remarks, Rowe said she had to consider both aggravating and mitigating factors as she made her ruling. She noted Williams’ history of violent acts as well as his documented history of mental illness.
As he was being led out the courtroom, Williams screamed that he needed to be moved into the general prison population and stated that he was being assaulted in the county jail, repeating a claim that he made earlier during an at times meandering testimony during the sentencing hearing.
Williams’ outburst drew an angry dismissal from Rogers’ father, Brian. “You’ll be dead within a year,” the elder Rogers said, cursing at Williams.
After about five hours of deliberation, jurors on Jan. 23 convicted Williams of second-degree murder, punishable by a minimum of 21 years and a maximum of life. The state had recommended the maximum penalty and the defense the minimum.
Rowe earlier had ruled that the state could not seek the death penalty for Williams, citing his longstanding mental health issues.
Ryan Rogers found dead after 2021 bike ride in Palm Beach Gardens
Ryan was a soccer-loving freshman at William T. Dwyer High School when he left his home in the Alton neighborhood along Donald Ross Road in Palm Beach Gardens for a bike ride on the evening of Nov. 15, 2021.
He headed south along Central Boulevard, and his body was found the next morning in a wooded area near the Interstate 95 overpass. Williams’ DNA was found on headphones near Ryan’s bicycle and under his fingernails.
Williams’ attorneys spent years building an insanity defense, arguing that his longstanding schizophrenia meant he could not understand right from wrong. Rowe ruled one month before the trial that their defense psychologist could testify to that effect.
However, on the eve of trial, Williams abandoned the strategy, switching his plea from not guilty by reason of insanity to not guilty. His attorneys told jurors he had stumbled upon Ryan’s body after someone else attacked him and kept moving, unaware the boy was bleeding or that he was a child.
“What happened to Ryan Rogers is undoubtedly a tragedy. No one in this courtroom will disagree with that,” Stephanie Gagerie, Williams’ lead public defender, said during her opening statement at his trial. “But Mr. Williams is not responsible for that tragedy.”
Williams’ mental competency was brought into question before and during the trial. He testified on his own behalf over the span of two days and spoke of being a victim of gang-stalking, a topic on which he had posted a series of videos on YouTube in the years before his arrest.
In one video posted in the days after the attack, he spoke of people on bicycles attacking him.
From the witness stand, Williams told jurors that Freemasons, a fraternal order dating to medieval times, and other organizations with ties to law enforcement and government had followed him with the intent of injuring him.
He also moved twice to fire his attorneys, telling the judge in a handwritten note on Jan. 22 that their poor performance had denied him a fair trial. Rowe denied Williams’ request to represent himself, citing his history of mental-health issues.
Williams had spent the weeks before Rogers died homeless and living on the streets of Miami, where he received help from at least one nonprofit that helps the transient.
He has no known ties to Palm Beach county, and it remains unclear what led him to travel to Palm Beach Gardens or to the area along I-95 where he encountered Rogers.
