A man has been sentenced to four years in prison for a high-speed crash that killed a woman from Carbon County.

Police say 26-year-old Laura Sheard and her boyfriend died after Daniel Habeeb hit their car in Seattle in 2011.

Sheard was from Jim Thorpe, but was studying for her PHD at the University of Washington.

Investigators say Habeeb previously struck and killed a woman in 2009.

Habeeb blames the crashes on "psychotic episodes."
