BERNALILLO, N.M.—Authorities say a Sandoval County sheriff's sergeant struck by a vehicle while directing traffic on Interstate 25 near the San Felipe Pueblo has died.

Sandoval County Sheriff Doug Wood released a statement Friday evening, mourning the death of Sgt. Robert Baron. He says Baron was not only a member of the law enforcement community but he was his friend.

Wood and other members of the department had been holding vigil with Baron's wife and 10-year-old son after doctors induced a medical coma.

Baron was initially listed in critical condition when he was transported to the hospital.

Officials say the 47-year-old Baron was hit in the aftermath of a snow storm Thursday.

Baron had been with the sheriff's department for seven years.
