Details are limited, as it's an active investigation, but Sheriff Ed Gonzalez announced via Twitter, how deputies were called to a home in the 8500 block of Majesticbrook. Initial details were it was a graduation party taking place with several teenagers attending, but was later revealed to be an after-prom party. 

Responding officers found Isaac Zetino, 16, who was hit by the gunfire and later died from their injuries. Sheriff Gonzalez said he and another teenage boy got into an argument with a girl's father.

It's unclear what the argument was about, but the sheriff said both groups pulled out weapons and a gunfight ensued. Investigators found the man who exchanged gunfire with the two teens and cooperated with officers saying "he had acted in self-defense when he was shooting." 

The father's statements were corroborated, based on what investigators found at the scene, and no charges appear to be filed "on any parties" at this time. 

Instead, Sheriff Gonzalez said the case will be investigated and presented before a grand jury to determine possible charges.

No additional information, as of this writing, has been shared, but an investigation remains underway.
