Documents detail social media post that led to Tempe City Council evacuation in August

In August, Tempe police evacuated the City Council chambers, citing a bomb threat posted on social media.

Documents obtained by KJZZ detail the events that caused the City Council to meet remotely for weeks.

Kathleen Tierney from Tucson was arrested last month on suspicion of making the threat.

Tempe police say they received a screenshot of a comment section including a post from an account allegedly owned by Tierney.

A redacted police report said the screenshot included the statement “... watching tonight’s council meeting,” and had an attached image of a silhouetted person overlooking the valley with a mushroom cloud erupting.

That same day there was a report of a suspicious male at City Hall trying to find council chambers, though police determined there was no crime.

Tierney worked at Cox Communications. The company says she no longer works there but would not confirm the position she held.
