According to the suspect, he ran to the car still carrying the machete to see if the driver needed help and that the driver pulled out a gun from the glove box and started firing at him, prosecutors said.
In reaction, he swung the machete at the driver, severing the 21-year-old's left hand. Minutes later, a large vehicle drove up from a nearby grilling area, and two men jumped out and punched the suspect multiple times in the face, prosecutors said the 22-year-old recounted.
The suspect was treated in a hospital for injuries to the face and released after being interrogated, prosecutors said. The investigation is still underway, but prosecutors said they were considering whether he acted out of self-defense.
The man whose hand was severed was treated in a hospital and reported to be in stable condition. Police determined that the weapon he fired was a starter pistol only capable of shooting blanks.
