The Clark County sheriff's department has identified the gunman in a Wal-Mart shooting as 35-year-old Shaun Michael Sprague of Gillette, Wyoming.

Sprague was booked Wednesday into Clark County Jail on a charge of first-degree assault.

Authorities say Sprague opened fire inside a Wal-Mart in southwestern Washington state early Wednesday morning.

No one was hurt in the shooting just north of Vancouver.

Deputies responded to the store after getting a report of an active shooter just before 7 a.m. The store was open at the time of the shooting.
