The suit alleges that the man, Edgar Ledezma Garcia, had fired into Rendon’s home and forced his way inside. Police were dispatched after a 911 call. Body-camera footage described in the complaint shows Rendon on top of Garcia in the doorway, punching him, before Valenzuela ordered Rendon to show his hands and fired.

Rendon was not the person officers were seeking and was unarmed, the lawsuit says. Valenzuela later told Arizona Department of Public Safety investigators that he believed Rendon was stabbing Garcia. In a recorded interview, the officer said he believed he had to shoot because people had made it sound as though the man was threatening or killing people inside the home.

The complaint includes 13 counts, among them excessive use of deadly force, wrongful death, unreasonable seizure, assault and negligence involving police hiring and training. Some claims are brought on behalf of Rendon; others concern friends and family members who witnessed the shooting.

“We decided each and every person who witnessed the crime, because I believe it was a crime, should be a plaintiff,” attorney David Chami said.

Chami previously filed a $25 million notice of claim against Phoenix. The lawsuit does not specify a dollar amount for damages, instead asking that compensation be determined at trial. A city spokesperson declined to comment, citing ongoing litigation.

The Maricopa County Attorney’s Office declined to prosecute Valenzuela in April. County Attorney Rachel Mitchell said she did not believe there was a reasonable likelihood of conviction.

Chami has argued that the shooting reflects problems in police training and a pattern of excessive force at the department. “You can’t comply if within less than a second of that command, you shoot the person,” he said, referring to the order to show hands.

The allegations have not been resolved in court. The lawsuit seeks to hold the officer, the city and other police personnel responsible for the fatal shooting and its impact on witnesses.
