There was an incident at Lincoln where a 20-year Special Ed student was thought to have a knife. That triggered a shelter-in-place for about 15 minutes. It turns out it was a plastic toy knife. SPD responded and spoke to the student.
SPD were called to the Rainier Beach area around 2:30 pm with a call of shots fired in the air by a guy who took off on foot. This was at 50 Ave S and South Rose. SPS put Dunlap, RBHS, South Shore Pk-8, Bailey Gatzert and South Lake on shelter-in-place while police checked out the scene. (Bailey Gatzert was on shelter-in-place simply because an SPD officer happened to be visiting the school, heard the call and asked for it to be enacted until he/she had more info.)
This shelter-in-place was about 20 minutes and was not associated with any SPS student or staff member.
