A 19-year-old man who opened fire on a group of people along the Cowles Mountain trail in San Carlos has been sentenced to one year in jail and two years of probation.

Jesus Castaneda pleaded guilty to a felony charge of assault with a semi-automatic firearm in connection with the March 30 shooting. No one was injured during the incident, which took place in the morning hours on the popular hiking trail.

Initial reports from San Diego police indicated that a woman had fired an unserialized “ghost gun” during an argument on the trail. Authorities later clarified that the shooter was actually a man — later identified as Castaneda — who had been accompanying the woman. She was not charged.

According to an anonymous witness quoted by the San Diego Union-Tribune, the shooting occurred after a group of young men began chasing Castaneda and the woman while holding rocks. During the foot pursuit, Castaneda allegedly turned and fired four shots at the group, while around a dozen other hikers were nearby.

At Castaneda’s sentencing hearing, San Diego Superior Court Judge Dwayne Moring stated the defendant “endangered public safety by discharging a firearm near innocent civilians.”

Castaneda was sentenced in two separate cases — one involving the Cowles Mountain shooting, and another for illegally possessing a firearm. Prosecutors noted that while he had been out of custody following the shooting, he violated a court order by obtaining another firearm. Jail records show he was booked back into custody last month.
