LENEXA, Kan. -- Stacy Michaels is a nurse and mother of three who always takes care of her neighbors.
One of them just happens to be a major retailer.
"I mean Costco is three houses down," Michaels said of her street in Lenexa.
On Sunday taking care of neighbors took on a whole new meaning, when a man waving a gun walked into the Costco right by her house.
"I heard about 8 to 10 rounds go off," Chris Morrissey, who was shopping at the store, said.
Shoppers and employees ran to the exits, frantic to escape the gunshots. Lenexa police later said an off-duty police officer shot and killed the suspect.
"It was a stampede. I mean everybody ran," Denise Meyer, a Costco employee, said.
When the stampede streamed down Michaels' street, her instincts to help kicked in.
"I said just open the house. Everybody that wants to, please go inside," Michaels said of her reaction.
She estimates 150 people ended up in her home and front yard. Many of them used her phone to call family members, since their cars were trapped for hours behind crime scene tape in the Costco parking lot.
Michaels' kids Molly and Max also jumped in to help, offering food and drinks to stranded shoppers.
"I was so incredibly proud of them. They went and gathered every water bottle we had and were walking with a laundry basket of water bottles and inviting people to use our bathroom," Michaels said with tears in her eyes.
While she praised her kids, Michaels doesn't want any recognition for what she did on Sunday. If you ask her why she opened her doors, she'll say it's just what any good neighbor would do.
"When people were thanking me, I told them you would do this for me if I was in your neighborhood," she said.
