by | Jan 17, 2024 | Department News, News Releases

On Wednesday, January 17, 2024, at approximately 8:45 a.m. Antonee Haines (41 years old of Tracy) was arrested at the Superior Court of California, County of San Joaquin – Manteca Branch by the Tracy Police Department’s Special Investigations Unit (SIU) for murder following a several months-long Fentanyl overdose death investigation.

In May of 2023, Travis Gassaway, a 39-year-old male, was found deceased by family members at a residence in Tracy. During the initial investigation, Patrol Officers located evidence at the scene suggesting Gassaway suffered an overdose from a counterfeit prescription pill containing Fentanyl. The investigation was continued by SIU over the next several months and Haines was identified as the suspected dealer of the Fentanyl used by Gassaway. In August of 2023, a search warrant at Haines’ residence in Tracy was served and resulted in the seizure of 367 M30 pills – suspected Fentanyl, 684 suspected Adderall pills, 124 suspected Alprazolam (Xanax) pills, suspected Psilocybin mushrooms, ammunition, over 9 pounds of Marijuana, and conditions likely to produce injury or death to his minor children. Haines was arrested and booked into the San Joaquin County Jail and charged with numerous drug-related crimes. With the assistance of the San Joaquin County District Attorney’s Office Investigators and Deputy District Attorneys, SIU continued investigating the case and ultimately discovered evidence necessary to obtain an arrest warrant for Haines for murder.

Tracy Police Chief Sekou Millington stated, “The arrest of Antonee Haines for Murder underscores the grave consequences of the fentanyl crisis that continues to plague our communities. This case reveals the dangerous intersection of drug distribution and fatal outcomes. Our relentless pursuit of justice aims to send a strong message that those responsible for distributing lethal substances will be held accountable for the devastating impact they have on individuals and families in our community.”

Haines was arrested for PC 187(a) – Murder and booked into the San Joaquin County Jail. This investigation was a collaborative effort by our Patrol Officers, Crime Scene Technicians, Special Enforcement Team, General Investigations Unit, and Crime Analyst.
