Police Detective Charles Hoffacker reportedly worked a double-shift over Memorial Day weekend, the incident happened at some point during that time period.
Four people were killed and 15 were wounded over Memorial Day weekend.
"This was an isolated incident that happened during a very, very difficult time for New Orleans and for this officer also," Hoffacker's attorney, Eric Hessler, told WWLT. "And I'm hoping that the NOPD sees it that way and treats it that way."
Hoffacker has already been decommissioned and given a desk job.
The detective has had pieces of his work displayed in art galleries in the past and he received a formal art education at Delgado Community College.
"I use art to bring the violence I experience on a daily basis to the forefront of the more cultivated art world," Hoffacker wrote on his website. "Art to ignite reflection and artistic creation to spur a dialogue of resolution is the underlying purpose of pursuing this career. I find solace in the tradition of painting to both memorialize and reason my subject matter."
