District Attorney Collin Sims announces that today (Tuesday, May 12, 2026), 41-year-old Deontrel Jermane Jackson of Slidell, Louisiana, was sentenced to 99 years at hard labor. The sentence follows Jackson’s March 2026 conviction by a St. Tammany Parish jury for Aggravated Crimes Against Nature involving a victim under the age of 13.

The Honorable Judge Scott Gardner presided over the sentencing. During the proceedings, Jackson was "double-billed" under the habitual offender statute, resulting in the 99-year term. Per the court's order, 25 of those years are to be served without the benefit of parole, probation, or suspension of sentence.
The investigation, conducted by the St. Tammany Parish Sheriff’s Office Special Victims Unit, revealed that between 2019 and 2020, Jackson repeatedly abused a juvenile at a residence in Slidell. The abuse was discovered after a journal entry was found in which the victim detailed her distress. During the trial, Assistant District Attorneys Gary Tromblay and Taylor Nicholson presented evidence of Jackson’s repeated predatory behavior and his own admissions of guilt.
Reflecting on the nature of the case and the defendant's actions, Assistant District Attorney Taylor Nicholson noted the clear violation of trust and law. "There is no ambiguity here; an adult cannot sexually touch a juvenile," Nicholson said. "The defendant admitted to his actions in his own words, and today the court ensured those actions have permanent consequences."
Assistant District Attorney Gary Tromblay emphasized the repetitive nature of the abuse during the proceedings. "This was not an isolated incident; it was regular, repeated, and predatory," Tromblay stated. "The defendant treated a child as an object for his own dark purposes. This sentence ensures he can no longer pose a threat to the children of our community."
District Attorney Collin Sims expressed his approval of the lengthy sentence. "Our priority is the safety of our children and holding those who harm them fully accountable," Sims said. "The 99-year sentence handed down today reflects the gravity of these crimes and the profound betrayal of safety suffered by the victim. I commend ADAs Tromblay and Nicholson for their hard work, and the Sheriff’s Office for an investigation that led to this significant result."
