Roberta “Bert” Carlson, a Washington state fan, died the morning of July 2 after a Saturn SUV she was driving overturned. Carlson and her four passengers were on their way to the Las Vegas Westercon. The rollover occurred between Ely and Wells on U.S. 93 in east-central Nevada, closing the highway for about three hours.

“Bert” Carlson, 43, of Bothell, WA was killed at around 5:45 a.m. after her SUV started to leave the roadway and she overcorrected, causing the vehicle to roll onto its roof. Three other occupants — Jon Foster, 37, from New Westminster, BC, William M. Boyde, 42, from Lynnwood, WA, and Heather M. Newman, 19, from Tacoma, WA — were transported to the Ely hospital with minor injuries. The fourth, Nick Navota, 28, from Port Orchard, Wash., suffered severe injuries to his left side and was flown to a Las Vegas hospital.

Everyone in the vehicle was wearing their seatbelt, said the Nevada Highway Patrol.

“Bert” Carlson was treasurer of the Seattle 2011 Worldcon bid, a Rustycon 26 Board Member, and a popular volunteer at Northwest science fiction conventions including OryCon.
