Jurors in a San Antonio federal courtroom listened to a profanity-laced voicemail Tuesday as prosecutors opened their case against Sergio R. Tapia, accused of threatening to kill a park ranger at San Antonio Missions National Historical Park. Tapia, arrested in July 2023, is charged with making an interstate communication that contained a threat to injure. His attorneys told the jury the menacing message was the product of a psychotic episode, not a real plan for violence.
Jurors Hear Chilling Voicemail
Prosecutors played the voicemail for the jury and said the caller identified himself as Tapia. The message repeatedly referenced a park employee and included graphic, profanity-heavy threats, including "I'm gonna (expletive) murder him" and "his days are numbered." The recording ended with a noise prosecutors described as sounding like a gun being cocked and fired. A ranger checking the office phone at Mission San José and other staff members recognized the voice, according to prosecutors, and Tapia was arrested on the federal charge on July 26, 2023, San Antonio Express-News reported.
Defense Says Threat Came From Mental Crisis
In opening statements, Tapia’s public defender told jurors the defendant was in the middle of a psychotic episode when the voicemail was left and argued he should not be held criminally responsible. "Tapia is not guilty," the defense said, pointing to what they described as a history of mental-health struggles and childhood exposure to illegal drugs. The defense cast the call as the outgrowth of serious illness rather than a genuine intent to follow through on the violent language, according to the San Antonio Express-News.
What the Federal Charge Carries
Tapia is charged under a federal law that makes it a crime to transmit threats in interstate or foreign commerce. Under 18 U.S.C. § 875(c), sending an interstate communication that includes a threat to injure carries a maximum sentence of five years in prison. The penalty can rise to up to 20 years if the threat is connected to an extortion demand, according to the statute itself, which is summarized by LII / Cornell Law School.
Inside the Missions Visitor Center
San Antonio Missions National Historical Park runs ranger-led programs and operates a visitor center at Mission San José, where staff handle front-desk calls and provide visitor services. Those day-to-day operations are outlined by the National Park Service and help explain how employees would have encountered and retrieved the threatening voicemail.
The trial is ongoing. Jurors were seated late Monday and testimony began Tuesday. Prosecutors say the case will hinge on whether the panel decides the recording was a true, prosecutable threat or the product of a mental-health crisis.
