An 18-year-old California high school graduate lost his entire hand when an illegal firework exploded seconds after he lit it outside a Pleasanton In-N-Out Burger restaurant, serving as a stark warning just days before Fourth of July celebrations.

Instant Destruction in Restaurant Parking Lot

The teenager, identified as Hanna, was with friends at the fast-food restaurant when a classmate handed him a tennis ball-sized firework wrapped in foil. The explosive detonated immediately upon ignition, completely destroying his right hand. Hanna described the horrific moment to local reporters, saying he looked down after the blast and saw nothing where his hand had been. The force of the explosion disintegrated the entire appendage instantly.

His twin brother Ramsey immediately called emergency services while desperately searching the parking lot for severed pieces of tissue to bring to the hospital. Friend Kevan Mokashi rushed inside the restaurant to get additional help calling 911. Responding police officers applied two tourniquets to stop the massive bleeding before paramedics transported Hanna to a trauma center. Despite emergency surgery, doctors could not save the hand but successfully preserved his wrist for future prosthetic attachment.

Investigation Reveals Illegal Explosive

Pleasanton Police Lieutenant Nicholas Albert confirmed investigators determined the firework was an illegal device, not one of California’s approved consumer fireworks classified as legal varieties. The group had been lighting fireworks in the parking lot on multiple summer evenings, treating it as routine entertainment after getting food. Hanna believes the explosive was defective, though authorities could not determine its origin. Police declined to cite the injured teen given the severity of his trauma and concluded insufficient evidence existed to pursue criminal charges against whoever sold or distributed the dangerous device.

Life-Altering Consequences and Recovery

Though left-handed, Hanna faces significant challenges relearning basic tasks like brushing teeth, dressing, and driving without his non-dominant hand. He missed graduation celebrations and postponed starting college to focus on recovery and eventual prosthetic fitting. The Pleasanton Police Department issued a public safety warning using his case as an example, emphasizing how fireworks can permanently alter lives in mere seconds. Despite the devastating injury, Hanna expressed determination to succeed, stating the accident motivated him to achieve greatness rather than accepting an average future without his right hand.
