Police took a 15-year old into custody in connection to a mass shooting at the Seattle Center that left three dead and several others injured. Police later said that 15-year old had a “ghost gun."

This refers to a type of firearm that’s often assembled at home and manufactured without a serial number.

In charging documents, prosecutors allege the teenager fired into the crowd. Police say the gun doesn’t appear to be involved the deaths of two bystanders from last week.

Washington is a leader in trying to prohibit ghost guns.

Back in 2022, the state passed a law to ban them. Earlier this year, lawmakers prohibited the unlawful manufacture of guns using 3-D printers or CNC milling machines.

And yet, ghost guns continue to be a concern here in the state.
