The family of an unarmed man killed last week by Wichita, Kansas, police after a fake 911 call led them to his location wants the officer who fired the fatal shot to be criminally charged , the familys attorney told HuffPost Wednesday.

Andrew Finch, 28, was killed Thursday evening in a suspected swatting hoax, a dangerous prank associated with online video games like Call of Duty where someone tries to draw large numbers of police officers to an address by telling emergency responders a made-up story. None of the Wichita officers involved were SWAT members, Police Chief Gordon Ramsay told The Wichita Eagle .

Our perspective is there needs to be a thorough investigation into the unjustified shooting of Andy Finch, said Chicago civil rights attorney Andrew M. Stroth, who is representing the family.

When the family thinks of justice, they think the officer should be held accountable for his actions that evening, he continued, adding that the Wichita Police Department and the city of Wichita are also liable for the death.

A 25-year-old Los Angeles man, Tyler Barriss, was arrested Friday on suspicion of making the call, which involved a fake hostage situation. Barriss appeared in a Los Angeles court Wednesday to say he would not fight efforts to extradite him to Kansas, where a case against him was presented to the Sedgwick County District Attorneys Office on Tuesday.

Lisa Finch, Andrews mother, wrote a letter Tuesday to local government officials including Ramsay and pleaded to see her sons body, which had not been released, The Associated Press reported . Stroth confirmed the Finch family has still been unable to retrieve Andrew Finchs body.

In her letter, Lisa Finch said the city of Wichita was compounding our grief and sorrow by holding the body of her son, whom she wanted to give a proper funeral service and burial .

Please let me see my sons lifeless body, she continued. I want to hold him and say goodbye. Please immediately return his body to us.
