SMITHFIELD, N.C. — Authorities have recovered the body of a 4-year-old boy who had been swept away in floodwaters in North Carolina.

The Raleigh News & Observer reported Thursday that the boy's body was found about 30 yards from where the body of his 5-year-old sister was found on Wednesday.

The children were swept away late Monday after their mother's car slid into fast-moving water in a creek near the Neuse River.

The children's mother, Vanessa Castro, survived.

The car left the road in Smithfield in Johnston County, which is southeast of Raleigh.
