Teen Athlete Dies After Contracting Brain-Eating Amoeba

Michael Riley died after being infected with naegleria fowleri

— -- The family of a 14-year-old athlete has confirmed that he died after being infected with a deadly amoeba that attacks the brain.

Michael Riley is believed to have contracted the amoeba during a swim in a fresh water lake, and his family posted a message on a Facebook page dedicated to supporting his health battle.

"Michael fought a courageous fight over the past week, allowing him to move on to be with the Lord for future heavenly tasks, a beautiful set of wings, and a pair of gold running shoes," the family's message reads.

"The tests tonight produced undesirable results which were coupled with the inability to function without support and proper blood flow to the brain," the statement says.

The so called "brain-eating amoeba" occur naturally in fresh water and can cause irreversible damage or death if they infect a person through the nose. Cases are rare, but deadly and only a handful of people are known to have survived the infection.

The Harris County Public Health & Environmental Services reported they were notified of a suspected amoeba infection Aug. 22, but could not confirm the teen was the patient due to privacy reasons.

Michael's family initially told ABC News affiliate KTRK-TV in Houston, Texas that they believed the teen contracted the dangerous infection on Aug. 13 during a trip to the lake with his teammates.

The teen, who qualified for the Junior Olympics three times, and was playing in the lake alongside his new high school track teammates.
