Amy Schumer is beside herself following a horrific incident in which a gunman open fired into a crowded movie theater playing her film Trainwreck in Lafayette, Louisiana, leaving two people dead and nine injured.

The shooter, who has been identified as 59-year-old John Russell Houser, has been described as a "drifter" who was staying in a motel by police, according to the Associated Press.

The outlet reported that after opening fire, he tried to flee the theater, but saw police near the exit and turned back into the crowd and shot himself. The shooter died of a self-inflicted gunshot wound.

"My heart is broken and all my thoughts and prayers are with everyone in Louisiana," Schumer wrote on Twitter on Thursday.

Schumer's bawdy comedy grossed $30 million its opening weekend and has been critically acclaimed as well.
