Detaron Lee Fenley will spend the rest of his life in prison after a Collin County jury convicted him of sexually assaulting a woman in Plano last year. Prosecutors said Fenley zeroed in on people he met online, including sex workers and immigrants he believed would be less likely to go to police, and several other women took the stand to describe similar attacks. The case that led to the conviction centered on a Sept. 24, 2024 assault, when the victim told investigators Fenley forced his way into her room, held a knife to her neck, tried to bind her and left her unconscious.
The life sentence came after jurors heard days of testimony and saw stacks of evidence. According to FOX 4, prosecutors introduced cellphone records and surveillance footage that placed Fenley at the scene of the attack. Investigators arrested him in October 2024 after matching his movements and communications to the victim’s records, and multiple witnesses later described assaults that followed a similar pattern.
How Investigators Say He Lured Victims
A Collin County grand-jury report shows Fenley was indicted on aggravated sexual assault and aggravated assault with a deadly weapon charges. Local reporting, including The Dallas Express, details how investigators pulled surveillance video, license-plate-reader hits and cellphone data to lock in on a suspect, and how DNA then linked him to a similar 2020 case in which the victim ultimately did not cooperate. Authorities say one of the assaults took place at a Studio 6 on Central Expressway in Plano, where the attacker put a knife to a woman’s throat and tried to tie her up before she escaped and sought medical treatment.
Prosecutors: "A Dangerous Sexual Predator"
Collin County District Attorney Greg Willis did not mince words in comments to FOX 4, calling Fenley a dangerous sexual predator. Willis pointed to a recorded jail call in which Fenley suggested that victims’ immigration status would keep them from testifying. He clearly told us who he was and what his next plans were, Willis said in the report. After hearing the evidence, jurors returned a guilty verdict and the judge handed down a life sentence this week.
What The Conviction Means For The Case
The conviction follows grand-jury indictments filed late last year and a trial that leaned heavily on forensic evidence along with live witness testimony. Prosecutors argued that the life term was necessary to protect the community, citing the pattern of alleged attacks described in court. Collin County court records list the case numbers and charges that have moved through the county’s criminal docket, and the grand-jury filing remains available in the public record.
Authorities are still looking for anyone who may have information about Fenley or similar incidents. As police advisories and local coverage note, tips can be directed to the Plano Police Department Special Victim's Unit tip line at 972-941-2044. Investigators say the probe is ongoing and that additional information from the public could help identify other potential victims.
