** ALTHOUGH THE FLYER SHOWS SALES GOING FROM 9/13-10/3, THE SALE HAS BEEN EXTENDED TO 12/13**
The Washington County Sheriff’s Office is asking our community to come together and support one of our own, Detective Brent Klingeman, and his son, Lucas, as Lucas faces another difficult battle with leukemia.
Lucas has been fighting since he was just two years old. In 2021, following what appeared to be a minor fall, doctors discovered a life-threatening brain bleed. Lucas underwent emergency brain surgery and spent weeks in the PICU, where further testing revealed that he was also battling leukemia.
After years of treatment, hospital stays and countless procedures, Lucas reached an incredible milestone in September 2024 when he rang the bell at Cardinal Glennon, marking the end of his treatment.
Sadly, that celebration was not the end of his journey.
On July 20, 2026, Lucas’ family learned that his leukemia had returned. He is now battling Mixed Phenotype Acute Leukemia (MPAL), a rare and aggressive form of the disease. Lucas is responding to treatment, but his road ahead remains uncertain, and his medical team is working toward the possibility of a bone marrow transplant.
Throughout everything Lucas has faced, he continues to show an incredible strength and resilience that inspires everyone around him.
As a Sheriff’s Office family, we stand with Detective Klingeman, his family and Lucas. We know that our law enforcement family extends far beyond the walls of our office, and this is a time when we can show that support in a very real way.
If you are able, we encourage our community to consider contributing to Lucas’ fundraiser. Every donation, share, prayer and word of encouragement can make a difference for the Klingeman family as they navigate this difficult chapter.
Please keep Lucas, Detective Klingeman and their entire family in your thoughts and prayers.
He fought before. He’s fighting again.
💙 LUCAS STRONG 💙
