At the time of the incident, Guzman, a 12-year-old, and a toddler were at home. Guzman's parents were reportedly not home at the time.

Police were originally told by a minor in the house that they were outside in the front yard when they heard a gunshot that was possibly coming from a grass field near the home.

The minor said Guzman ran inside and he put away a lawn mower. The minor then told police he found Guzman upstairs unconscious.

Police later questioned the minor with his parent present. He told police the location of a handgun after saying that he was playing with a bullet and it went off.

There have been no arrests made.
