OGDEN -- Prosecutors are laying out their case against one of three men who were riding in a motorboat when it severed a swimmer's legs and killed the woman, a University of Utah scientist.
A jury was seated in Ogden on Monday in the case against 22-year-old Skyler Shepherd, who owns the motorboat.
Shepard told police another defendant was driving when it hit Esther Fujimoto on Aug. 21, 2011, at Pineview Reservoir, seven miles east of Ogden.
Shepherd told authorities he took the wheel to circle back on the swimmer. The boaters have said they left the woman in the water after she reported she was OK.
A medical examiner determined the 49-year-old Fujimoto died from propeller wounds. She was part of a University of Utah team that identified a breast cancer gene.
