A Brazoria County sheriff's deputy who fatally shot an 18-year-old man in Lake Jackson, Texas, has been fired, a significant turn in a case that has drawn intense scrutiny. The sheriff announced the termination of Deputy Kevin Tippett in a video statement, even as the dead teenager's family pressed for him to face criminal charges over the killing.
The deputy, Kevin Tippett, shot and killed John Mendoza Jr., an 18-year-old who was a student at Texas State University. According to authorities, the deadly encounter unfolded on June 1, when Tippett tried to pull over Mendoza Jr. Rather than stopping, the teenager kept driving and eventually came to a stop in the garage at his own home.
It was there that the encounter turned fatal. Officials say the deputy fired his gun following the encounter, striking Mendoza Jr., who later died at the hospital. Surveillance video from the scene captured the sound of a single gunshot, and dispatch audio from that night included the words accidental discharge, a phrase now at the center of the questions surrounding the case.
On Tuesday, the Brazoria County sheriff shared a video statement announcing that Tippett, the deputy who shot and killed Mendoza Jr., had been fired. In his remarks, the sheriff said his responsibility was to take action where he could and to allow independent processes to proceed where he could not, adding that the authority entrusted to law enforcement officers is extraordinary and comes with a responsibility to exercise it carefully.
For Mendoza's family, the firing was not enough. Speaking outside his home after the termination was announced, the teenager's father called for the deputy to be arrested and charged with murder. He argued that any other person in Brazoria County who shot and killed an unarmed teen on camera would be arrested and charged with murder, and said he was glad such a person was off the streets.
The father also pressed authorities to make the evidence public. He called on the Brazoria County Sheriff's Office and the district attorney to release all of the video and audio footage from the night his son was killed, framing transparency as central to the family's pursuit of accountability. He named the deputy directly, saying Tippett needed to be charged and indicted with murder.
The shooting remains the subject of an outside investigation. The Texas Rangers, the state's investigative arm, are examining the circumstances of the encounter, a step that places the inquiry in the hands of investigators outside the local sheriff's office that employed the deputy. With Tippett now fired but not charged, the case moves into a phase in which the family's demand for prosecution and the independent review will help determine what comes next.
In the weeks that followed, newly released documents offered a clearer picture of where the case stands. According to a search warrant, investigators recovered evidence including the former deputy's pistol, and the Texas Rangers said they had probable cause to investigate potential offenses in Mendoza's death, including manslaughter, criminally negligent homicide and aggravated assault by a public servant. Officials stressed that these were listed as offenses under investigation and not criminal charges, and that the warrant had been obtained to seize the weapon for forensic testing rather than as an indication that charges would be filed.
