WEST HARTFORD, Conn. – A Connecticut doctor whose wife and two daughters were killed in a 2007 home invasion has remarried.

Dr. William Petit, 55, wed 34-year-old photographer Christine Paluf on Sunday. About 300 people attended the ceremony in West Hartford and the reception in Simsbury, said Rick Healey, a friend and family spokesman.

Paluf met Petit while working as a volunteer for the Petit Family Foundation, a charity set up by Dr. Petit in memory of his family after the killings in Cheshire. The foundation helps educate young people, improve the lives of those with chronic illnesses and protect those affected by violence.
