Tyler Tennigkeit was arrested and booked on suspicion of attempted murder.
Wednesday morning, he was detained and questioned at the scene of a traffic crash on Santiago Canyon Road not far from the Jackson Ranch Equestrian Center. Investigators say he was under the influence at the time.
Later that night, sheriff's deputies served a search warrant at his home next to the center and found a weapon, along with shell casings outside that matched the weapon.
No injuries were reported in the incident, but witnesses said they heard bullets whizzing by them and ricocheting off trees. When the shots rang out, deputies said a mother managed to help three people, believed to be children, leave the center. Seven to eight others, however, were told to stay in place at the center, officials said.
A motive for the shooting remains unknown. Authorities say Tennigkeit has prior narcotics and weapons charges on his record.
A woman who was in the home where authorities believe the shots were coming from was detained as a person of interest, but her role in the incident remains unclear.
