Comedian Amy Schumer expressed her deep condolences on Thursday shortly after police confirmed that three people were shot and killed at a movie theater during a screening of her film “Trainwreck” in Lafayette, Louisiana.

“My heart is broken and all my thoughts and prayers are with everyone in Louisiana,” she wrote on Twitter.

The American Film Institute also offered “heartfelt sympathies” to the victims in Lafayette.

“Going to a summer movie is a celebration of the American creative spirit and one of our nation’s most beloved pastimes,” AFI President and CEO Bob Gazzale said. “Let us stand together in these times of tragedy and embrace what is precious to us — churches, schools and places where the arts can send our spirits soaring.”

Police said the unidentified gunman — described as an older, white male — opened fired during the 7 p.m. screening of “Trainwreck” at the Grand 16 Theater. He later shot and killed himself.

Seven people have been hospitalized in Lafayette — three of which suffered critical injuries.
