According to TMZ, Neidhart's wife Ellie told investigators that on August 13, 2018, he was having problems sleeping and got out of bed to adjust the thermostat. As he went to touch it, he "turned weirdly as if he were about to dance", then fell against the wall and ground. She immediately dialed 911, believing he was having a seizure, something for which he took medication. He had a four-inch long gash on his face when EMTs arrived. He died at the scene at the age of 63. According to the Pasco County Sheriff's Office, the fall killed him. At the time, he had early-onset Alzheimer's disease.
