A woman curling her eyelashes in her car was mistaken for a person with a gun and prompted a lockout at two Boulder schools on Wednesday, the day after a school shooting in Highlands Ranch.

Both Casey Middle School, 1301 High St., and Sacred Heart of Jesus School, 1317 Mapleton Ave., were placed on lockout this morning in “an abundance of caution” just after noon Wednesday for a report of a woman in her vehicle holding a gun in the air.

Police spokeswoman Shannon Aulabaugh said police found the woman and took her into custody. Aulabaugh said police did not find any weapons and believe the woman’s eyelash curler was mistaken for a gun.

The schools returned to normal operations at about 12:30 p.m..

Boulder police already had increased presence at local schools Wednesday due to a shooting Tuesday at a school in Highland Ranch that left one dead and several others injured.

Following a school shooting in Florida in 2018, there were two separate incidents in which a pressure washer and a wooden color guard rifle prompted lockouts and lockdowns at Boulder-area schools.
