Castillo allegedly picked up a Glock 22 from the ground at Union Station, where the celebration was being held. Witnesses stated that the gun was dropped by one of the shooting suspects during the commotion.

Upon picking up the firearm, Castillo was ordered by the police to the ground and subsequently arrested for unlawful possession of a weapon. Reports mentioned that he appeared intoxicated, with slurred speech and bloodshot eyes at the time of the incident. Castillo, a convicted felon, maintained that he believed the gun belonged to an officer and intended to turn it over to the authorities.

Castillo, who has a prior felony conviction for marijuana possession in Kansas, insisted that he was merely trying to help and was not involved in the altercation that led to the gunfire.
