Jeopardy! star Alex Trebek and his wife, Jean, just donated $500,000 to Hope of the Valley Rescue Mission to help fight the homeless crisis in the Los Angeles area. The money help fund the construction of a new central facility that will include a shelter for homeless seniors, a medical facility, a commissary and administrative space for the group. Hope of the Valley has 15 facilities in the San Fernando Valley, including two that are under construction, and serves 839,000 meals per year. The donation was a huge surprise because the couple had already given Hope of the Valley $100,000 earlier this year.
