Update for Sept. 20
Four people are in jail after gunshots were fired from the Fox Hole Apartments on S.W. 160th St. into windows and cars at the Southwest Seattle Ambulatory Center on Sept. 19, according to the arrest record released by the King County Sheriff's Office.

The shooting led to tense moments for students, faculty and parents at nearby Three Tree Montessori and Sylvester Middle School as both went into lockdown mode while police secured the area.

No one was injured.

A 16-year-old female was arrested for reckless endangerment and is considered the alleged shooter. The juvenile had a warrant out for her arrest and was booked into King County Youth Services.

Also inside the apartment where police made the arrests were 20-year-old and 21-year old males booked for investigation of controlled substances. A third male, 20, was arrested for investigation of possession of a stolen firearm and possession of a controlled substance.

Drugs and guns found inside the apartment

The following information comes from the KCSO incident report:

The initial 911 call from the Southwest Seattle Ambulatory Center at 275 S.W. 160th St. was for fireworks.

As the responding officer drove to check it out another 911 call came in changing the call to gunshots.

As the deputy reached the scene she heard bullets fly by her patrol cruiser. Once inside, the officer was led to the first floor break room with a bullet hole in the window and shattered glass on the floor. An employee was sitting in the break room when bullets hit the window, but escaped unharmed.

The deputy went to the second floor break room to investigate several more bullet holes when she looked out the window and saw a white male and female on a Fox Cove Apartment balcony.

When they saw police had responded to the scene, the eventual suspects ducked quickly into their apartment and closed the blinds.

The deputy worked her way to the ambulatory center roof and set up surveillance on the apartment while a search warrant was secured.

Deputies entered the apartment and found the female and two males locked in a bedroom.

Two firearms, a .22 caliber rifle and a .38 caliber revolver, were recovered from the scene along with meth, pills, cocaine and marijuana.

The .38 caliber revolver had been reported stolen.
