ST. LOUIS (AP) — Some enterprising children who wanted to help a suburban St. Louis officer who was shot during a traffic stop had a lot of helpful and generous customers.

The 10 children organized a lemonade stand in West St. Louis County Sunday to raise funds for Ballwin Police Officer Mike Flamion. He was in critical but stable condition Monday after being shot from behind by a man he stopped for speeding on Friday.

KMOX reports the kids hoped to raise about $20 but ended the day with $4,000 for the Flamion family.

One of the children’s mother, Kate Gieseler, said a Dierbergs store donated all the items when store officials heard what the children were doing. Several police and fire officials came to the stand Sunday to lend support.
