Corona police Cpl. Tobias Kouroubacalis said that only six tickets were bought for the movie on Monday night and they believe Jimenez acted alone in the shooting. 

"It was completely unprovoked, and the victims were shot without any kind of prior contact," Kouroubacalis said Wednesday.

"Look at me. Look at me!" Goodrich yelled at Jiminez as several people held him back, according to FOX 11. "That was my daughter."

Theater workers found the wounded teens after the 9:35 p.m. showing of "The Forever Purge," which is the fifth installment in the series that depicts a dystopian future of America where all crime is legalized for 24 hours annually.
