The family of a New Hampshire woman who disappeared in Maine has offered a $5,000 reward for information leading to her safe return.

Sarah Rogers, 29 of Barrington, N.H., has been missing since Dec. 13, when her car was found in the median of Interstate 95 in Clinton. Police suspect she may have been picked up by a passing motorist.

Rogers is married and has a 2-year-old son.

Police plan a major search in the Clinton area in the spring, once the snow melts.

Investigators ask that anyone with information contact authorities at 800-4452-4664.
