A Milwaukee County jury yesterday found 58-year-old former gas station security guard William Pinkin guilty of first-degree intentional homicide in the 2023 shooting death of 29-year-old Isaiah Allen. Jurors also convicted Pinkin on a related felony weapons charge after roughly 20 minutes of deliberations, sending the case into a second trial phase to determine whether he is not guilty by reason of mental disease or defect.
Pinkin took the stand in his own defense this week and told the court, "I don't remember pulling the trigger. The gunshot woke me up," at times giving answers that clashed with earlier statements, according to FOX6 Milwaukee. After he openly challenged the authority of the court, the judge ordered him removed from the courtroom, and he was not present when jurors returned their verdict.
How Prosecutors Say The Shooting Unfolded
Prosecutors introduced surveillance video that they say shows Allen reaching for a box of Little Debbie snack cakes inside the Clark gas station at Teutonia and Roosevelt, while Pinkin sits in a chair at the back of the store, according to TMJ4. The footage appears to show Pinkin rising, following Allen outside, and firing a shot that struck Allen in the head. The same video appears to capture Pinkin returning inside after the shooting and picking up the snack cakes, a sequence prosecutors leaned on to question his version of events. Pinkin turned himself in to authorities two days after the August 16, 2023, killing.
Past Conviction And Why That Matters
Court records show Pinkin was previously convicted in a 1990 homicide and spent many years in prison before a series of releases. Reporting indicates he was released again in March 2023 and was still on supervision at the time of Allen's death, which meant he was barred from legally possessing a firearm, according to WISN 12. Prosecutors cited that history in pressing the weapons charge and framed it as context for the state's case in Allen's killing.
Next Legal Steps
Because Pinkin has maintained a plea of not guilty by reason of mental disease or defect, the guilty verdict does not end the case. Instead, it triggers a second phase in which a jury will decide whether he was criminally responsible at the time of the shooting, FOX6 Milwaukee reports. If that jury rejects the mental-disease defense, Pinkin faces the mandatory penalties that come with a first-degree intentional homicide conviction, including a possible life sentence. The mental-responsibility phase of the trial is expected to take place next month.
Community Response And Licensing Fallout
In the months since the shooting, Allen's family and neighborhood residents have held protests outside the Clark station at Teutonia and Roosevelt, pressing city officials to respond. Amid that pressure, the Milwaukee Common Council's licensing committee recommended revoking the gas station's license, and the business has remained closed, according to Urban Milwaukee. Allen's relatives have described the shutdown as part of their broader push for accountability after what they call a senseless death.
Broader Questions Around Private Security
Security industry experts told local reporters the case highlights serious gaps in how some Milwaukee businesses hire and train guards, including situations where armed workers are unlicensed or receive minimal training, TMJ4 reports. Advocates and several alderpersons say the verdict should sharpen debate over background checks, training standards, and whether cash-strapped businesses are cutting corners on safety when they put armed guards between customers and the checkout counter.
