Park City siblings charged in Vernon Hills gunfire incident that locked down schools

A Park City man and his sister have been charged in connection with a shots fired incident that shut down schools last week in north suburban Vernon Hills.

About 8:45 a.m. Sept. 17, a Vernon Hills resident stepped out of their home in the 300 block of Plumwood Court after hearing the sound of gunshots, Vernon Hills police said.

The resident allegedly saw Ulises Jacobo, 20, standing near the resident’s vehicle with a handgun, while his sister, 18-year-old Guadalupe Jacobo, smashed it up with a baseball bat, police said.

A warrant was released for Ulises Jacobo’s arrest the next day, charging him with reckless discharge of a firearm, mob action and criminal damage to property, police said. He turned himself in Sept. 23.
