A Sacramento civil rights attorney has leveled a lawsuit at the Lodi Police Department.   

Attorney Mark Merin represents the family of Parminder Singh Shergill.  

Shergill, a Gulf War veteran known to be suffering from PTSD, was shot and killed Jan. 25, during a confrontation with Lodi Police.  

Merin is filing suit against the city of Lodi to shake loose the details about that officer involved shooting.

"We need this. The community wants it. The family wants it. Nothing. The only way you get information under this system is to follow a lawsuit," Merin said in an interview with News10. 

The family is disputing the account from the Lodi Police.  

Meanwhile Lodi Police have said the investigation by The San Joaquin County Sheriff's Department says could take a year to finish.
