SEATTLE (KOMO) -- At least four people were injured in five separate shootings on Interstate 5 between Federal Way and South Seattle on Monday night, according to Washington State Patrol (WSP).

Troopers first posted on X about the shooting incidents at 9:27 p.m., noting the first one occurred on northbound I-5 at 320th, where a passenger was injured. WSP said shortly after the shooting occurred, the 911 caller exited the freeway and drove to a nearby fire station, where their injuries were treated before being taken to Harborview Medical Center. The victim told WSP the suspect's vehicle description was a white Volvo with California plates.

Fifteen minutes later, WSP said it received another call regarding a shooting that occurred on northbound I-5 at MLK. No victims were harmed in the shooting, and only a vehicle sustained damage, according to WSP. At this time, there is no suspect vehicle description in connection to the second shooting, WSP said.

Shortly after the second reported shooting, sometime between 8:45 and 8:50 p.m., WSP received a call reporting a shooting that occurred at northbound I-5 at I-90, where a passenger was injured. There is no suspect vehicle description that has been provided by WSP.

The Seattle Fire Department (SFD) said after the third shooting incident its crews treated a 20-year-old woman who was reported to be in critical condition. She was driven to Harborview Medical Center shortly after, according to the SFD.

WSP said with the help of the Tacoma Police Department, Lakewood Police Department, University Place Police Department, Puyallup Police Department, Pierce County Sheriff's Department and Fircrest Police Department all assisted in the arrest of the suspect after locating the suspect vehicle.

It's unclear if all of the shootings are connected.
