After an investigation, authorities have confirmed that a 12-year old girl from Alexandria drowned while longboarding, a type of skateboarding back in late April. JaLysa Cook was found in about three feet of water between Lakes Cowdry and Darling on the west side of Alexandria. Cook was taken to the hospital where she died. The Douglas County Sheriff’s Office says Cook entered the water on her own before getting swept up in the current and going underwater.
