The daughter of former Democratic presidential hopeful Howard Dean (search) and four other young women were taken to a hospital Sunday after their sport utility vehicle rolled over on Interstate 91, state police said.

Anne Dean (search), 20, was treated and released from Yale-New Haven Hospital, said a hospital spokeswoman, who would not describe the nature of any of the women's injuries.

State police said Mona El Sayed, 17, of Tinton Falls, N.J., was the driver of the Ford SUV, which is owned by Howard Dean. The hospital spokeswoman said El Sayed was still being evaluated Sunday night.

The three other women — Betty Townsend, 18, Eliza Berman, 19, and Catherine Hillin, 19, were all treated and released.

Anne Dean is a junior at Yale University. Broadcast reports said the women were apparently returning to Yale from Vermont, where the Dean family lives.

State police said the vehicle was traveling southbound on I-91 in North Haven when it drifted onto the grass median, moved back into the left lane and spun out of control before rolling over in the median.
