 Authorities say damage from Hurricane Beryl is what caused the 911 outage in South Dakota Tuesday night. Lumen, the telecom company that provides 911 service to Sioux Falls, informed city officials that damage to the network infrastructure caused the outage. The autopsy results from a 22-year-old man whose body was found last month in the Missouri River have been released. The report says Philip Snoozy of Yankton drowned and there were no signs of foul play.
