Craig Manders, 72, of Cranford, N.J., states in court papers that African Portfolio, Inc., failed to protect him and his wife, 70-year-old Lisa Manders, who was killed while on a “bush walk” tour in Zambia.

A New Jersey man whose wife was killed in a horrific hippopotamus attack last year during a safari in Africa is suing the U.S. company that arranged the trip, alleging it failed to ensure their safety and did not adequately screen and supervise the tour guides.

The tour company's attorney said, “My client didn’t conduct the safari. It arranged it. It booked all the components.”
