An attorney representing Lisa Finch, the mother of a man who was killed by Wichita police last week after a "swatting" prank call, is calling for criminal charges to be filed against the officer who fired the fatal shot.

"Justice for the Finch family constitutes criminal charges against the shooting officer," attorney Andrew Stroth told the Associated Press in a phone interview.

The tragic death of Andrew Finch, 28, began with a prank phone call. A man called Wichita police claiming that he had shot his own father, taken his family hostage, and poured gasoline around the home. The caller claimed to be at the address where Andrew and Lisa Finch actually lived.

In reality, there was no hostage situation, and the caller had no connection to the Finch family. But police didn't know that, so they surrounded the house and demanded that Finch come out of the house. Finch came out the door with his hands up. But then he briefly lowered his hands, and a police officer shot him. The officer says he feared Finch was reaching for a gun tucked into his waistband. In reality, Finch was unarmed.

On Friday night, Los Angeles police arrested Tyler Barriss for allegedly making the prank call. The call apparently came in the wake of an online dispute between two Call of Duty players. The intended target of the attack allegedly lied to Barriss about his address, leading to a police raid of an innocent man—Andrew Finch—with no connection to the online dispute.

This kind of prank—calling police with a fake emergency in hopes of getting a SWAT team sent to a target's house—is common enough in the gaming world that it has a nickname: "swatting."

But the Finch family puts the responsibility for Andrew's death at the feet of the Wichita police department. And Lisa Finch faults the city of Wichita for its handling of the situation after the shooting.

“It goes without saying that our family is devastated by what has happened,” Finch wrote in a letter to city officials. “What cannot go without saying is why Wichita City leadership is compounding our grief and sorrow, by keeping my son from us? Please let me see my son’s lifeless body."

The letter says police have yet to return the family's front door as well as a computer, two cell phones, and other items that were taken in the wake of last week's shooting.
