Limestone Jury Finds Ex-Wife Guilty of Murder

On Monday, October 30, 2017, a Limestone County jury deliberated two hours before finding Mary Jacoby guilty of murdering her ex-husband, Raymond Keith Jacoby. The jury determined that Mary Jacoby, either acting alone or as party to the offense, shot and killed Raymond Jacoby with a firearm on March 31, 2011.
County Attorney Roy DeFriend, and his Assistants, Beth Toben and Jeff Janes, called approximately 25 witnesses and introduced over 150 exhibits during the six-day trial, which began Monday, October 23rd. The witnesses included some of the former co-workers and customers of the Mexia Recycling/Scrapyard, which was owned by Mr. Jacoby and where the Defendant, Mary Jacoby worked. The jury also heard from current and former officers and investigators with the Mexia Police Department and the Texas Rangers, ballistics experts from the Austin DPS lab, gunshot residue (GSR) experts from the Tarrant County Medical Examiner’s office, and Dr. Lynn Salzberger of the Southwest Institute of Forensic Science, who performed the autopsy. Jurors viewed videotapes from patrol cars at the scene, heard taped statements of Mary Jacoby, and reviewed cell phone records.
The Defendant elected to have the Honorable Deborah Oakes Evans, 87th District Judge, assess her punishment. After receiving the jury’s guilty verdict, Judge Evans, who presided over the trial, ordered the Limestone County Community Supervision Department to prepare a pre-sentence investigation (PSI). A PSI is an investigation into the history of a defendant convicted of a crime, which is used by a court in assessing a punishment. The sentencing phase of the trial will be November 20, at 1:00 pm.
Murder is a first degree felony with a punishment range of 5 years to 99 years or life in TDCJ-ID, and a fine of up to $10,000.00 can also be assessed. The Defendant will have to serve one-half of whatever sentence is imposed before she can even be considered for parole.
“This jury verdict shows that criminal conduct like this won’t be tolerated in Limestone County,” stated County Attorney Roy DeFriend. “I would like to commend the Mexia Police Department, the Texas Rangers, Mexia Fire Dept./EMS, and others too numerous to mention, for a job well-done. Without their tireless assistance, this verdict would not have been possible.”
