New Chicago Police Supt. David Brown offered his gratitude Wednesday to four children who crafted and donated personal protective equipment for police officers.

“Thank you so much for being here and sharing your innovations and public service with us,” Brown said. “What you are doing for us is saving lives.”

“We should get you on ‘Shark Tank,’ and have you pitch other ideas you might have.”

Sariah Stagen, 9, and her sisters, 7-year-old twins Arianna and Alessandra, met the superintendent Wednesday at police headquarters. The girls, who live with their parents in Humboldt Park, brought with them a batch of homemade hand sanitizer and gave Brown a demonstration of how they made it.

James Stagen, the girls’ father, is a Chicago police officer assigned to the Shakespeare District on the Northwest Side.

Giovanni Alonzo, 10, crafted plastic strips designed to lessen irritation around officers’ ears that can be brought on by constantly wearing protective masks. Engraved in the strips was the phrase “Hero At Work.”

Alonzo, whose family lives in Garfield Ridge, also gave Brown a handmade card to thank first responders for their service during the COVID-19 pandemic.

As of Tuesday, more than 400 employees of Chicago Police Department had tested positive for COVID-19 and three officers have died of the virus.
