Sorry, that is incorrect.
New Vista High School is less than 300 feet from the King Soopers that got massacred.
Also, the shooter once lived, or was still living, about one mile away on Table Mesa Drive.
His south Boulder address is on one of those Crime Info websites that teases you with a drop or two of information, and then makes you subscribe for the whole file.
The reports I heard referred to Boulder High School, and the 2nd locale the police went to was about a block away from Boulder High School. I never heard a report referring to New Vista High School.
I lived in Boulder years ago, so I’m pretty familiar
