Jennifer Lees

Jennifer Lees, 57, of O'Fallon, MO., passed away Saturday, September 26, 2026 at her home of COPD.

Jennifer was born on June 5th, 1969, in St. Louis, MO, to Richard and Barbara (nee Busch) Lees. Richard preceded her in death.

Jennifer was a mother of three children: Joshua Hall, Brianna (Alexis) Gatses, and Victoria (Harry) Hall and step son Justin (Marianne) Hall ; her significant other and life partner, Robert Cooley; grandchildren, Annabel, Natalia, Camden, Jonah and Miguel; brother, Brian (Michelle) Lees, one half-brother and two half-sisters, friends, and a host of other family members.  

She is preceded in death by her grandson, Braxton Hall - who was welcomed into Heaven at birth.; One half-sister preceded her in death; and other family members.  

Jennifer graduated from Hazelwood Central High School in 1987 and was administrator of their Facebook Page up to this present time.  

Jennifer enjoyed going to Indian Pow-Wows and being as active as possible.  She loved animals and at one time had two dogs and three cats. She chose her final resting place beside her beloved Robert, wanting them to remain side by side in life, and one day, in rest.

As she became less active due to illness, she watched her birds during the day, which kept her entertained.
