A Bexar County judge sentenced a San Antonio man to 70 years in prison Friday after jurors convicted him of murder and tampering with evidence in the fatal stabbing of a 52-year-old man at a Northeast Side bus stop.
The sentence closed the main trial phase of a case that prosecutors said was driven by jealousy and unfolded in minutes near a busy stretch of Northeast Loop 410. Carl Mott, now 62, was convicted Jan. 30 in the killing of Michael Duran Bowman, who authorities said was stabbed on Dec. 14, 2024, while standing with his wife. Prosecutors said Mott had been in a long-term affair with Bowman’s wife, then fled and discarded the knife near his own workplace. The case mattered not only because of the deadly attack in public, but because investigators said surveillance video and eyewitness testimony quickly turned the stabbing into a tightly documented homicide case.
Judge Ron Rangel imposed the 70-year sentence on March 6 in Bexar County’s 379th Criminal District Court, a little more than five weeks after the jury returned guilty verdicts. By that point, prosecutors had already laid out a simple but highly personal theory of the case. They said Bowman and his wife arrived at a bus stop on the Northeast Side on the morning of Dec. 14, 2024, when Mott approached them and exchanged words with Bowman. Prosecutors said Mott then pulled a knife and stabbed Bowman in the upper left shoulder. Police said the attack happened just before 7 a.m. near the 2600 block of Northeast Loop 410. Bowman, badly wounded, made it into a nearby business seeking help. He was taken to a hospital with life-threatening injuries but later died. The Bexar County Medical Examiner’s Office later identified him as Michael Duran Bowman and ruled his death a homicide caused by a sharp injury to the chest.
The evidence described by prosecutors centered on what happened after the stabbing as much as on the attack itself. According to the district attorney’s office, surveillance footage showed Mott discarding the knife in bushes near his place of employment about 10 minutes after the assault. That detail supported the tampering charge and gave investigators a trail they could test against witness accounts and the morning timeline. Police said they used security footage to identify and track Mott, then arrested him about 11 hours after the stabbing at his West Side home. The knife was recovered four days later, according to prosecutors. The state also relied on testimony from Crystal Bowman, the victim’s wife, who prosecutors said had been involved in a long-standing extramarital relationship with Mott. Public statements from the district attorney’s office did not spell out every earlier interaction among the three adults, but prosecutors repeatedly described the killing as an act fueled by jealousy rather than a random confrontation or street crime.
That context shaped nearly every public account of the case. What officers first announced in December 2024 was a deadly stabbing and a same-day arrest. As the prosecution moved forward, the outline became far more specific. Prosecutors said the attack happened at a bus stop, in front of Bowman’s wife, after words were exchanged. Local reporting at the time said Bowman and his wife identified Mott as the attacker after rushing into a nearby restaurant for help. By the time of sentencing, the district attorney’s office had tied the case to a relationship history that made the violence both more personal and more disturbing. District Attorney Joe Gonzales said in a statement that the killing was a “senseless act of violence fueled by jealousy.” Even with that description, some details stayed outside the public record. Authorities did not publicly lay out the full content of the exchange before the stabbing, and they did not release a fuller courtroom narrative describing whether the encounter had been planned in advance or was a sudden confrontation when the couple reached the stop.
The legal result was severe, but the case does not erase the ordinary setting in which it unfolded. Bowman was not attacked in a secluded place or during a dispute hidden from public view. He was at a bus stop near a major roadway early in the day, then staggered into a nearby business looking for help. That sequence gave the case a grim immediacy in local coverage. A routine morning commute turned into a homicide scene, followed by a video-based search that ended with an arrest by evening. The prosecution also added weight to the evidence-tampering count by saying Mott tried to rid himself of the knife near work instead of keeping it or dropping it near the scene. In court, that kind of detail can matter because it speaks not only to identity but also to conduct after the crime. It gave prosecutors a narrative arc that moved from confrontation to flight to concealment, with surveillance footage connecting each step. Jurors accepted that account when they convicted Mott on both counts in late January.
Friday’s sentence resolved the murder case at the trial-court level, but it did not close every matter connected to Mott’s time in the criminal courts. KSAT reported that Bexar County court records show he is also awaiting trial on a separate aggravated assault with a deadly weapon charge stemming from an Oct. 16, 2024 incident. Public reporting reviewed for this article did not show that the separate case had been resolved as of Sunday, March 8, 2026. In the murder prosecution, prosecutors treated the sentence as a measure of accountability for Bowman’s death and for the pain caused to his family. Gonzales said the punishment ensured that Mott would be held accountable and that justice had been delivered for the victim and his relatives. The larger public record, though, remains narrow and factual: a bus stop confrontation, a single stabbing, a wounded man seeking help, surveillance footage showing where the knife went, and a jury that found the state had proved murder and evidence tampering beyond a reasonable doubt.
As of Sunday, March 8, 2026, the case stood with a 70-year prison sentence in the Bowman killing and no widely reported new public development beyond that judgment. The next visible milestone is likely to come from any appeal in the murder case or from court action in the separate aggravated-assault case still listed against Mott.
